The Cage

Stardate: Unknown

The original pilot of the series had the encounter of the Enterprise at Talos IV. It is this encounter which prompts the issuance of General Order 7--the only death penalty the Federation has.

Captain Christopher Pike is captured by the Talosians to become the father of many human slaves for the repopulation of the planet's surface.

Where No Man Has Gone Before

Stardate: 1312.4

Several years before this second pilot, the S.S. Valiant had flown to the edge of the galaxy. At the edge, it found an energy barrier. Something in the barrier made the Valiant 's captain destroy the ship.

The episode begins with the Enterprise finding the Valiant 's disaster record-marker. Just prior to its destruction, the crew of the Valiant had been searching library tapes for anything they could find concerning psionics. The Enterprise reaches the edge of the galaxy and encounters the same force which affected the Valiant . The psionic abilities of Garry Mitchell, a longtime friend of Kirk's, and Doctor Elizabeth Dehner are heightened--much like the Captain of the Valiant . With the heightening of their psionic powers, they become more dangerous. Mitchell declares himself to be a god who will rule over humanity. His death is the only thing that can solve the situation. Eventually Dehner realizes how inhumane Mitchell has gotten and attempts to help Kirk kill Mitchell. However, Mitchell kills Dehner without remorse. Kirk is able to cause a landslide to kill and entomb his long-time friend. It is the first time Spock admits to feeling something close to human emotion.

The Corbomite Maneuver

Stardate: 1512.2

The Enterprise is exploring an uncharted region of space when it encounters a space buoy warning ships away and blocking the starship's path. Kirk orders the buoy destroyed, but a large alien ship, shaped like a giant crystal, traps the Enterprise . Balok appears and accuses the Enterprise of trespassing and committing hostile actions--actions which require the destruction of the Enterprise . Kirk bluffs that any attack on the ship would cause the corbormite in the ship's hull to self-destruct, destroying both ships.

Balok takes the ship in tow, but Kirk wrenches the ship away so quickly that it disables the alien ship. The Fesarius sends out a distress signal which the Enterprise hesistantly answers. Kirk, McCoy and Lieutenant David Bailey beam aboard the Fesarius to find that Balok is merely a friendly, child-like entity. Balok grins as he reveals his own bluff to Kirk--testing the Enterprise to see if they were really as peaceful as they claimed. A small diplomatic relationship begins and Bailey stays behind as an exchange student to learn more about Balok's people and teach him about the Federation.

Mudd's Women

Stardate: 1329.1

The Enterprise pursues an unknown ship into an asteroid field to save its crew before it's destroyed. Four members of the crew are rescued-Harry Mudd and three women. Mudd was transporting the women to Ophiuchus VI to marry settlers. However, the Enterprise burned out its lithium crystals while chasing Mudd's ship. Kirk ordered the ship to Rigel XII, the nearest lithium mining planet. When they arrive, it is quickly seen that Rigel XII is inhabited only by three lonely, single lithium miners. The three women, who use an illegal Venus drug to keep themselves beautiful, end up marrying the miners in exchange for the lithium crystals. When the fraud is discovered, the miners are not angry, but keep their new wives just as they are.

The Enemy Within

Stardate: 1672.1

In orbit of Alfa 177, the Enterprise experiences a transporter malfunction when Technician Fisher beams aboard with a metallic ore on his clothing. Scotty checks the transporter, but sees nothing wrong. Kirk beams aboard. When the transporter room is deserted, the transporter reengages and a second Kirk materializes. A dog-like animal is beamed aboard, but it is immediately split into two entities--one tame and one vicious. It's discovered that the same thing's happened to Kirk. More transporter tests continued to produce split beings. Therefore the landing party had to remain on the planet and weather the freezing temperatures until the transporter is fixed.

As time passes, the good Kirk becomes more indecisive while the evil Kirk is dying. Scotty repaired the transporter, but the first test failed as the dog-like animal came back as one entity--but it was dead. Kirk takes his counterpart into the transporter and goes through the cycle. He materializes whole and alive. With this success, the landing party is rescued before any of them die from exposure.

The Man Trap

Stardate: 1513.1

The Enterprise delivers supplies to Dr. Robert Crater and his wife Nancy on planet M-113. Crater asks for only salt tablets. Several members of the away team end up dead with suction-cup marks all over their faces. There is a shapeshifting creature, which had killed Nancy Crater years ago, who is the last native inhabitant of M-113. She is let loose on the Enterprise under many guises where she kills several more members of the crew before she is killed by McCoy, who had once dated Nancy.

The Naked Time

Stardate: 1704.2

Spock and Joe Tormolen beam down to Psi 2000 to pick up a research team before the planet disintegrates. However, they find that the entire team has frozen to death after someone had turned off the life support. Stranger yet, every one of them seemed to have been out of their minds when they died.

Tormelon carries what is later known as the Psi-2000 virus back to the Enterprise . The virus is waterborne and spread on contact with perspiration. Sulu and Kevin Riley are affected while trying to keep Tormelon from killing himself. Sulu holds the Bridge crew hostage with a fencing foil while Riley declares himself Captain of the Enterprise and locks himself in Engineering where he turns off the ship's engines so that the starship will crash land on Psi 2000. McCoy manages to avoid contracting the virus in order to create an antidote.

Charlie X

Stardate: 1533.6

Charlie Evans arrives aboard the Enterprise by means of the S.S. Antares . When the Captain of the Antares tries to warn Kirk about Charlie's condition, the Antares is suddenly destroyed. Charlie's only concern is that his new "family" like and accept him. When he's angered anything can happen (e.g., he makes Yeoman Rand disappear and breaks Spock's legs).

Charlie demands that the Enterprise take him to the closest inhabited planet and leave him there. After Kirk refuses, Charlie takes control of the ship. Once Kirk is able to regain control from Charlie, a Thasian appears on the Bridge. The Thasians had raised Charlie after the ship he had been travelling on as a child crashed on their planet leaving him the only survivor. They take Charlie back and restore the Enterprise back to normal.

Balance of Terror

Stardate: 1709.2

The marriage of Angela Martine and Robert Tomlinson is interrupted when a Romulan warbird attacks and destroys Outpost 4, which guards the Neutral Zone between Federation and Romulan space. Kirk learns that the Romulan ship has also destroyed three other outposts and is now running at full speed towards home.

The Enterprise pursues the warbird, hampered by the fact that the Romulans have constructed an invisibility screen which shields them from view. While the screen protects the Romulans from detection visually, it also prevents them from using their weapons or visual aids. The Romulan Commander, therefore, isn't sure whether his radar is detecting a Federation ship in pursuit or a harmless space echo.

The Enterprise is able to pick up a visual from the Romulan bridge, which shows the previously unseen Romulans to look very much like Vulcans. This sparks an old prejudice in Lieutenant Andrew Stiles, whose family fought in the Romulan wars. He is instantly suspicious of Spock, whose physical characteristics are remarkably similar to the Romulans they are chasing.

After every attempt to lose the Enterprise fails, the Romulan Commander is forced to turn and fight. Both ships are damaged; when the Enterprise's phaser banks are damaged, they emit a poisonous gas which disables Stiles and Tomlinson, who are manning the weapons. In a tense race against time, Spock manages to fire the only remaining phaser manually, disabling the Romulan ship. The Vulcan manages to save Stiles, but Tomlinson is killed. Stiles, realizing by Spock's actions that his bigotry was misplaced, admits that he was wrong.

The Romulan Commander contacts the Enterprise and, in a stirring moment, tells Kirk that under other circumstances, he suspects they might be friends. Rather than let himself and his ship be taken prisoner, the Romulan self-destructs the warbird.

What Are Little Girls Made Of?

Stardate: 2712.4

The Enterprise arrives at Exo III to search for Dr. Roger Korby. Korby is Nurse Chapel's fiance. Korby allows only Kirk and Chapel to beam down to the planet. While he has been on the planet, Korby has learned how to make androids that look and act just like humans. This is found out when his chief aide fails to recognize Chapel. Korby intends to replace key people in the Federation with his androids.

Korby replaces Kirk with an android duplicate. However, Kirk plants false memories into the double's brain which makes it easy for Spock and the Enterprise crew to realize the fraud when he's in command of the ship. Kirk escapes from his imprisonment by helping his android guard realize the danger posed by Korby. Chapel quickly finds out that Korby is not the same man she fell in love with. He's housed his essence in an android body. The episode ends with a landing party beaming down to the planet shortly after Korby kills himself and his last remaining android.

Dagger of the Mind

Stardate: 2715.1

The Enterprise receives Dr. Simon van Gelder, a member of the psychiatric staff of the Tantalus Penal Colony, who is exhibiting signs of manic insanity. McCoy convinces Kirk to investigate the colony despite Kirk's objections. Once on the colony, Kirk finds that the head of the colony, Dr. Tristan Adams, has been using a neural neutralizer to effectively brain-wash the inmates and staff. Adams insists that Kirk try the machine himself--which makes him fall madly in love with Dr. Helen Noel, the Enterprise 's psychiatrist.

Meanwhile, on the Enterprise , Spock attempts to get information from van Gelder through a mind meld. Understanding what is going on with the neural neutralizer, Spock starts to plan an escape for the Captain. Dr. Noel escapes imprisonment through an air duct until she reaches the control room where she shuts down the planet's shield. Spock beams a landing party to the surface. Kirk fights Adams, finally knocking him into the neutralizer. Kirk, still dazed from his own experience with the machine, stumbles away. Adams is found dead by the landing party. van Gelder is made sane again and returns to direct the colony.

Miri

Stardate: 2713.5

The Enterprise answers a distress call to find an unnamed planet which appears to be an exact duplicate of Earth in the 1960s. Three hundred years before, the natives experimented with a virus that wiped out the adult population with rapid aging while making the life process of children last centuries before reaching puberty. The landing party contracts the virus and is quarantined to the planet until a cure is found.

The remaining children on the planet harass the Enterprise crew until Kirk convinces them that they too will contract the disease and die a horrible death. McCoy uses himself as a guinea pig to test an antidote found in the planet's lab and finds a cure. He suggests that the Federation send supervisory personnel to work with the children and help colonize the planet.

The Conscience of the King

Stardate: 2817.6

Twenty-two years ago, the governor of Tarsus IV, Kodos, evoked emergency martial law and ordered half of the planet's population executed. His intent was to address a severe food shortage on Tarsus IV, and it earned him the name "Kodos the Executioner." It was believed that Kodos died on the planet, but there is some belief that he may have escaped and assumed another identity.

James Kirk, Lt. Kevin Riley, and Dr. Thomas Leighton are the only surviving witnesses to Kodos' previous evil deeds; others who might have known Kodos have been mysteriously killed in various accidents.

A traveling theatrical troupe arrives at Planet Q, and a Dr. Leighton contacts the Enterprise regarding a new synthetic food concentrate. When he is beamed aboard, he tells Kirk that his real reason for contacting him was to tell the captain that he suspects Anton Karidian, the head actor in the theater troupe, is really Kodos.

When Dr. Leighton is murdered, Kirk agrees to transport the Karidian Players to the Benecia Colony on board the Enterprise. His real motive is to study Karidian and his daughter in an attempt to learn if he is, indeed, Kodos and responsible for Leighton's death.

When Riley is poisoned, the young man learns of Kirk's suspicions and goes to the theater on board the Enterprise to kill Kodos. Kirk stops him and takes the actor as his prisoner. Then he learns that Karidian's daughter, Lenore, has been killing anyone who might know of her father's past life. Karidian, who has been trying to forget his past, is horrified to find what his daughter has been doing. Lenore aims a phaser at Kirk, but her father steps into the line of fire and is killed. Lenore goes completely insane at having killed her father.

The Galileo Seven

Stardate: 2821.5

The Enterprise passes Murasaki 312 while on its way to Makus III. StarFleet had ordered them to inspect such galactic phenomena so Spock, McCoy, Scotty and four crewmen take the Galileo for a closer look. The shuttle is pulled off course so that Spock must crash land on Taurus II, a planet inhabited by giant humanoids. They land during a war between factions. Quarrels amongst themselves stifle the crew's work to repair the shuttle.

On the Enterprise , Commissioner Ferris demands that Kirk call off the search for the shuttle and continue to Makus III. As the Enterprise prepares to leave the area, the Galileo makes it into an unsteady orbit of Taurus II. Spock ignites the remaining fuel to attract the Enterprise 's attention. The crew is beamed aboard as the shuttle disintegrates in the atmosphere.

Court Martial

Stardate: 2947.3

When the Enterprise puts in at Starbase 11 for repairs caused in an ion storm, Kirk gives his report of the circumstances of Lieutenant Commander Ben Finney's death to Commodore Stone. All goes well until Spock arrives with the computer visual tape of the bridge during the crisis. Spock tries to warn Kirk about what is on the tape, but the Commodore takes it and plays it. Kirk's statement claims that Finney went into the Enterprise's ion pod to take vital readings. When the storm made it necessary to jettison the pod, Kirk warned Finney during a yellow alert; he eventually switched to red alert before jettisoning the ion pod. This event occurred with Finney, apparently, inside.

What the computer tapes show is Kirk pressing the pod-release switch while still in a yellow alert status. As a result of this, the Commodore informs Kirk that he will have to stand trial for possible court-martial for the death of Finney. Things are complicated even more when Finney's daughter, Jamie, blames Kirk for her father's death.

When Kirk meets an old girlfriend, Lt. Areel Shaw, that evening she tells him that she's arranged for a lawyer to come and see him. Unfortunately, she's been assigned to prosecute his case and will try her best to bring him down. Dejected, Kirk goes to his room to find that Samuel T. Cogley has moved in, books and baggage. Kirk decides that he likes the quirky lawyer and they begin to plan the captain's defense.

On the Enterprise, McCoy reprimands Spock for playing chess with the computer while Kirk is on trial for murder. Spock explains that he has won several games straight ... a feat he should not have been able to accomplish unless the computer is malfunctioning. McCoy's interest is piqued and the two men discuss what this development could mean to the captain's defense.

At the trial, just as the defense has rested, Spock appears with the information about the faulty computer. Cogley gives a stirring speech about the rights of men versus machines and the Commodore finally allows the jury to reconvene on board the Enterprise.

Spock explains that having programmed the computer for chess himself just months before, the best he should have been able to do is stalemate. Therefore, the officer explains, someone tampered with the computer, adjusting its memory. When asked who had the knowledge for such an action, the Vulcan admits that it could only have been himself, Kirk or Records Officer Ben Finney. Cogley then suggests that Finney is still alive and hiding somewhere on the Enterprise.

On the Bridge, the ship's sensors have been boosted to pick up any sound on the ship. Everyone but the bridge personnel and transporter attendant are beamed to the surface and the demonstration begins. Switching on the sensors, everyone's heartbeat on the ship is audible. One by one McCoy, using a white-light masking device, eliminates the sound of everyone's heartbeat ... except one ... Finney's.

Kirk goes after Finney and finds him hiding on the ship. Finney has harbored a grudge against Kirk since they were both ensigns, when Kirk had logged a careless and potentially dangerous mistake of Finney's, which the man claims has kept him from promotion over the years.

The two men fight, with Kirk finally winning. Finney had, however, damaged the ship's engines and the Enterprise is losing its orbit. Racing against time, Kirk manages to repair the damage and the Enterprise regains her previous position. Kirk is cleared of all charges and Samuel T. Cogley takes on a new client ... Ben Finney.

The Menagerie

Stardate: 3012.4/3013.1

The Enterprise and her crew are diverted by a signal from the former captain of the Enterprise on Starbase 11, and proceed to the call. When they arrive they find Captain Christopher Pike, who is severely crippled by radiation burns, confined to a moving chair and his ability to communicate limited to the answers "yes" and "no."

Unbeknownst to Captain Kirk, Spock abducts Pike on board the ship. Captain Kirk returns to the Enterprise with Commodore Mendez, and soon discovers that Spock has locked the ship's controls on a course set for the planet Talos IV � a planet to which a visit carries the death penalty. Forced by the extreme actions of the Vulcan first officer, the two convene a court-martial against Spock.

During the proceedings, from an unknown source, they watch the events that transpired when Captain Pike was in command of the Enterprise. They are shown Pike's initial contact with the Talosians, a race of beings eager to study human beings in their natural state, and who can provide illusions to make things appear exactly as they would like. The transmission relays Captain Pike's entire mission surrounding the Talosians and their bizarre experiments while holding him in a powerful cage. The Talosians are telepathic beings, able to dig deep into the memories to find whatever illusion will be most effective. They attempt to hold Pike captive until his passion and fury force them to release him.

As the proceedings end, the entire court-martial is found to be meaningless, a result of Commodore Mendez being an illusion created by the Talosians for Kirk's benefit. The events, as well, which depicted Pike on Talos IV were also found to originate from the Talosians.

Because of Pike's condition, Spock has risked his career and freedom to bring his former captain to a place where he will be able to live an illusion of a pleasant life, rather than the tragically limited one he lives now. Kirk allows Pike to beam down to Talos IV and all charges against Spock are dropped.

Shore Leave

Stardate: 3025.3

An Enterprise landing party beams down to an uncharted planet. The planet seems like a perfect candidate for shore leave with its "Earth-type" characteristics. Kirk sends McCoy down with the party to check it out.

McCoy's first encounter on the new world is with a life-sized white rabbit in a waistcoat, being chased by a little girl in a pinafore. Kirk answers McCoy's somewhat odd call for help and beams down himself to find his old rival from his academy days, Finnegan. While trying to catch his old enemy, Kirk meets Ruth, an old girlfriend. He notices that neither Finnegan nor Ruth have changed in appearance since he's last seen them. Elsewhere, Sulu is attacked by a Samurai Warrior while others are chased by tigers and aircraft.

McCoy, who has paired off with Yeoman Tonia Barrows, is killed by a black knight on horseback. As the perils become more and more deadly, Kirk and Spock realize that their thoughts are somehow coming to life around them.

An old man appears, explaining that this planet is designed as an "amusement park," and he is the Caretaker for the world. The planet is not meant to be hostile, and the results of one's fantasies are not lasting. McCoy appears, healed, with a Rigel Cabaret girl on each arm. Tonia disengages the good doctor and they go off to spend what promises to be an enjoyable vacation together. The Caretaker invites Kirk and his crew to spend their leave on his planet. Kirk agrees, realizing that once warned, it would provide a most diverting vacation spot. As he makes his decision, Ruth appears.

The Squire of Gothos

Stardate: 2124.5

The Enterprise must cross an empty sector of space on their way to deliver supplies to colony Beta VI. In this space, they find an uncharted planet whose presence can't be explained. After Kirk and Sulu disappear without apparent reason, Spock orders McCoy and geophysicist Lt. Karl Jaeger to the planet's surface to begin a search.

They find Trelane, a humanoid with tremendous psionic powers and a passion for Earth's 18th-century military history. It is he, they discover, who impulsively kidnapped Kirk and Sulu, wanting to add them to his arena of the Napoleonic era that he has created on this planet, Gothos.

While Trelane has great powers, he has little self-control and is spoiled, willful and impetuous. When McCoy and Jaeger appear, Trelane invites them all to join him at his party.

Spock manages to beam them aboard the Enterprise, but Trelane, determined to have his way in all matters, transports the entire bridge crew to Gothos for a banquet. Kirk challenges Trelane to a duel and in the process, destroys the device the alien uses to create his illusions. However, Trelane repairs it and prevents the Enterprise from leaving orbit until he can punish Kirk for his rash actions.

In exchange for freedom for the Enterprise and her crew, Kirk offers himself as the prey in a "fox hunt." Suddenly, as Trelane is about to kill the Captain, two noncorporeal beings appear. They explain to Kirk that they are Trelane's parents, and apologize for letting their child play such dangerous games. They then scold the errant child for his selfish behavior and temper tantrums. They inform Trelane that he will not be allowed to have another planet to play with until he learns how to treat other beings with respect.

Arena

Stardate: 3045.6

The Enterprise is in pursuit of an unknown alien ship which has destroyed a Starfleet base on Cestus III. In an uncharted area of space, both the alien ship and the Enterprise are caught by an advanced race called Metrons. The Metrons are angry at the two ships for trespassing into their space and believe that physical combat is the answer to finding justice.

They transport Kirk and the alien captain, a lizard-like creature called a Gorn, to an uninhabited asteroid to fight to the death. The Metrons promise that the victor and his ship will be set free, while the loser will be destroyed, along with his ship and crew.

The Gorn informs Kirk that the base on Cestus III was destroyed because it was believed to be a hostile intrusion on Gorn space. The Gorn is seven feet tall and much stronger than a human, with an extremely aggressive nature, but Kirk has the advantage of speed and agility that his opponent lacks. Kirk manages to keep out of the Gorn's way long enough to mix local minerals into gunpowder, which he uses in a primitive cannon to wound the Gorn captain.

When Kirk refuses to kill the Gorn, the Metrons decide that there may be some hope for the human species after all. Both captains and their ships are set free.

The Alternative Factor

Stardate: 3087.6

While orbiting what should be a dead planet, the Enterprise experiences a moment of "nonexistence." Starfleet Command fears an enemy invasion and orders Kirk to find out what caused the stellar system disturbance.

On the planet below, Kirk finds a man called Lazarus, who tells Kirk that the effect was caused by his enemy. Lazarus has been chasing him with the aid of a time/space craft and wants the Enterprise's dilithium crystals to continue his search. The captain refuses.

When Kirk takes Lazarus aboard the Enterprise, it becomes apparent that there is something strange about their visitor. He has incredible mood swings, one minute sane and rational, the next exhibiting violent rage. He also has a bloody head wound that disappears, then reappears moments later.

Lazarus manages to steal the ship's dilithium and return to the planet. Kirk follows and discovers that Lazarus is two people--one sane and one a madman, with one from an anti-matter universe. The sane Lazarus informs Kirk that the beings can only appear in either universe one at a time. Should both men be in the same place at the same time, both universes would be destroyed. Kirk helps the sane Lazarus trap his counterpart in an intermediate time corridor where they can hurt neither the matter nor anti-matter universe, but where the two will be trapped in fight until the end of time.

Tomorrow Is Yesterday

Stardate: 3113.2

When the Enterprise is thrown into a time warp by a black star, it ends up orbiting Earth in the 20th century. Omaha Air Base detects a peculiar UFO and sends a fighter plane, manned by Captain John Christopher, to investigate.

The starship accidentally destroys the plane, caught in their tractor beam, so the pilot is beamed aboard. The problem now, of course, is to prevent Captain Christopher from returning to tell others on Earth. In order not to change history, in which Christopher's son will prove important, Kirk must return the captain to Earth without knowledge of the ship.

In an attempt to remove all records of the Enterprise sighting, Kirk and Sulu beam down to the air base. Kirk is almost immediately captured by the Air Police, though Sulu manages to escape and gets the stolen records to the Enterprise. Spock and Captain Christopher beam down to help get Kirk away from the Air Police. At the same time, an Air Police sergeant has been accidentally caught in the Enterprise's transporter beam and is reeling as he finds himself on a 23rd-century starship.

Spock and Scotty manage to recreate the conditions of the time warp that brought them to this time, with a slingshot effect around the Sun. The confused Air Police sergeant is returned to Earth a second before he was transported to the Enterprise, so he will remember nothing of his astounding experience, and the starship returns to the 23rd century.

This time, the pilot sees nothing and the Air Force concludes that the sighting was a mistake ... a UFO. In effect, everything that had happened, never happened.

The Return of the Archons

Stardate: 3156.2

The Enterprise is investigating Beta III, where the Archon disappeared over 100 years before.

When the landing party exhibits strange behavior, Kirk sends another party down to investigate. They find the culture on Beta III is quiescent, with no creative tendencies. The entire culture is controlled by a group of 'lawgivers' known as "The Body" which is, in turn, controlled by the omniscient Landru. The inhabitants change from normal, peaceful people to a violent mob at the coming of the Red Hour. This 'Festival' is the society's only outlet for the tyrannical hold that Landru has over them at all other times.

Meanwhile, the Enterprise is being pulled from its orbit, its crew to be absorbed into the Body. This, they discover, is what happened to the Archon, so many years before.

Archon survivors have formed an underground of sorts to fight the Body, and they help Kirk and Spock reach Landru. Landru turns out to be an incredibly complex computer built by Landru, a scientist who lived 6,000 years before, who wanted to guide his people into a peaceful, civilized progress.

Landru had affected the computer with his scientific thoughts and memories, but not his wisdom. For centuries the computer, 'Landru,' has been interpreting his suggestions to the point that no one is allowed independent thought. Kirk tells the computer that instead of helping to nurture the culture of Beta III, it has harmed it. Landru destroys itself, leaving the Betans to work toward the sort of culture Landru had wanted so many centuries before. With the promise of Federation help on the way, Kirk and his crew beam back to the Enterprise.

A Taste of Armageddon

Stardate: 3192.1

The Enterprise is ordered to pick up Ambassador Robert Fox, who is headed to planet Eminiar VII on a diplomatic mission. Upon arriving at the planet, the ship is warned away.

Beaming to the surface with a landing party, Kirk and Spock are met by a young woman, Mea 3, who tells them that Eminiar VII has been at war with its neighboring planet, Vendikar, for over 500 years. Mea 3 takes them to the council chambers where they find banks of computers. Eminiar's head council Anan 7 informs them that the two planets have learned to avoid the complete devastation of war because computers are used. When a "hit" is scored by one of the planets, the people declared "dead" willingly walk into antimatter chambers and are vaporized. Anan 7 further tells Kirk that his ship and all the crew aboard her have been declared casualties and will be executed. When Kirk flatly refuses, the landing party members are taken prisoner.

The council members are unable to convince Scotty, in charge of the Enterprise, to lower shields without a direct order from Captain Kirk. Meanwhile, Ambassador Fox has beamed to Eminiar and is also taken prisoner, marked for death. Kirk and Spock escape and gain the council chambers where they destroy the computers. Kirk tells the council members that they have made this war too easy for themselves and that they will truly experience the horrors of war if they do not learn to make peace first. Ambassador Fox volunteers to stay behind and negotiate a peace between the neighboring planets.

Space Seed

Stardate: 3141.9

A piece of one of history's great puzzles falls into place when Kirk's crew comes across theS.S. Botany Bay, an old-style, pre-warp sleeper ship from Earth that contains several bodies in stasis. Amongst these bodies is Khan Noonien Singh, a genetically engineered strongman and one of the great leaders of Earth's Eugenics War of the 1990s. Although he disappeared without a trace then, once Khan is aroused from his long sleep he soon reveals the ambition, strength and intelligence that helped him conquer a quarter of the Earth.

Once aboard the Enterprise, Khan quickly befriends the beautiful Lieutenant Marla McGivers, the ship's historian who has a passion for strong-willed leaders. Together with his Botany Bay crew and new companion, they seize control of the Enterprise by capturing the engine room. Before it's too late, Marla has great misgivings about her newfound loyalties. With her help, Kirk and Spock regain control of the ship by flooding it with gas. Khan's men are soon overtaken and a due punishment is meted out. Khan and his crew, including Marla McGivers, are exiled to a planet where they must start life anew.

This Side of Paradise

Stardate: 3417.3

Expecting the colonists of Omicron Ceti III to be dead after three years of exposure to deadly Berthold rays, Kirk and Spock are surprised to find the colony alive and flourishing.

Spock beams to the surface and meets a young botanist, Leila Kalomi, that he'd worked with previously, and they renew the old friendship. When she worked with Spock six years before on Earth, Leila had tried to interest Spock romantically, and failed. Now she leads the Vulcan to a secluded section of the planet where a native plant sprays him with their spores. Leila tells Spock that the plant induces feelings of harmony and peace and love, along with a desire to remain on Omicron Ceti III and their paradise.

The spores serve to break down Spock's inhibitions and soon he has declared his love for Leila and his desire to remain on the planet. Some of the plants are beamed aboard the Enterprise and more of the crew are affected.

Captain Kirk, the last holdout, finally is affected by the power of the spores and discovers, through his own violent, adverse effect at leaving his beloved Enterprise, that strong, violent emotions are what reverse the effect of the spores.

Kirk manages to lure Spock back to the Enterprise where he goads Spock into a fight. The extra adrenaline in the Vulcan's system pushes the effect of the spores from Spock and he reverts to normal ... just short of killing Captain Kirk.

Using subsonic sound waves, the two officers manage to bring around the rest of the crew and colonists. Now that the colonists realize that the spores have prevented them from making any real progress and accomplishments, they plan to relocate where the plants do not grow.

The Devil in the Dark

The Enterprise arrives to investigate reports of an unknown monster deep in the mining tunnels of Janus VI. The being is apparently destroying machinery and killing the miners, and has the ability to burrow through solid rock. Janus VI is a source for the rare mineral, pergium.

Soon after the landing party arrives on the planet's surface, a reactor pump is stolen and the colony is in jeopardy from fluctuating life support functions. However, this convinces Spock that they are dealing, not with a mindless monster, but with an intelligent lifeform.

Kirk and Spock, along with members of the ship's security team, enter the mines to find the creature. They discover a large, rock-like creature that burrows easily through the stone walls, as a mole might burrow through dirt. Wounded in a phaser blast, the bulky creature manages to escape through the stone wall.

They continue pursuit and eventually Kirk is trapped by the creature. When it doesn't attack, Spock attempts a Vulcan mind meld with the entity and discovers that it is, in fact, an intelligent being. A native of the planet, the creature is normally peaceful, and called a Horta. It doesn't mind sharing the planet with the miners, but when the men broke into the Horta's hatchery and unknowingly destroyed many of her eggs, it attacked to protect its remaining unborn children.

With Spock acting as interpreter, the miners explain that they thought the eggs were some king of silicon nodules and that no hostility had been meant.

McCoy treats the silicon-based creature with a trowel and patch material, and heals it. An alliance is formed between the Horta and the miners; the young, newly-hatched Hortas will mine the pergium at a far faster rate than the humans could and the miners will be extremely rich. Kirk retrieves the missing reactor and the landing party leaves the inhabitants of Janus VI living in peaceful co-existence.

Errand of Mercy

Stardate: 3198.4

Kirk and Spock beam down to the surface of planet Organia to negotiate for the erection of a Federation base on that planet. Hostilities between the nearby Klingon Empire and Federation have reached alarming heights and it is feared that the medieval culture of the Organians will not be able to withstand a Klingon attack. However, the Organian Council, comprised of five seemingly pleasant, benign elderly men, insist that they prefer to stay with their more primitive culture.

When Kor and his Klingon force attack the planet, Kirk and Spock go undercover as Organian and Vulcan traders. They are captured by the Klingons, and to their surprise, the Organians free them with ease. In turn, the Klingon ship and the Enterprise square off to battle in orbit of the planet.

Displeased by the outbreak of violence, the Organians reveal themselves to be powerful creatures of pure energy who easily neutralize the weapons on both ships, thus ending the threat for the moment.

Back on the Enterprise, Kirk feels certain that the Organians will not only take care of themselves in the future, but monitor their surroundings for any hint of hostilities.

The City on the Edge of Forever

Stardate: 3134

McCoy accidentally injects himself with an overdose of cordrazine, a drug which makes him exhibit signs of paranoia and madness, while treating an ailing Sulu on the Bridge. Delirious, he beams down to a nearby planet's surface, with Kirk and a landing party on his heels.

They are too late to stop the doctor from leaping through a living time machine called "The Guardian of Forever." At that moment, the Enterprise ceases to exist and the landing party is stranded. The Guardian explains that McCoy went back into Earth's history and changed it, thereby altering the future. Kirk and Spock go through the Guardian, to Depression-era America, a few days before McCoy is to arrive and change history.

They encounter a social worker, Edith Keeler, who helps them find work to pay for the equipment Spock requires to build a tricorder. Unknown to Kirk and Spock, Edith has taken in the recently-arrived and ill McCoy. Kirk promptly falls in love with Edith and is devastated when Spock completes his tricorder and discovers that in order to repair history, they must let Edith Keeler be killed in an auto accident. If they allow McCoy to save her, as he did before, she will start an effective pacifist movement that will delay the United States' entrance into World War II, thus allowing Hitler's Germany to develop the atomic bomb first and conquer the planet.

When the moment comes, a heartbroken Kirk stops McCoy from saving Edith, and the three officers journey back through the Guardian, where they find things as they should be again.

Operation: Annihilate!

Stardate: 3287.2

Arriving at the planet Deneva, home of Kirk's only brother Sam and his family, the Enterprise picks up a transmission from a Denevan pilot who has steered his craft into the sun to destroy some unknown menace.

Beaming down to the planet, Kirk finds his brother dead and Sam's wife in a fatal condition. Their only son, Peter, survives informing the landing party of what has occurred. It seems that Deneva has been infested with large, amoeba-like aliens that attack humans and intertwine their tentacles with the body's nervous system. They can move short distances through the air and use excruciating pain as a means of controlling their victims.

When Spock is attacked by one of the creatures, he uses his Vulcan mind control to overcome the pain and return to duty. However, a cure must be found; they must find a way to kill the parasite without harming its host.

Kirk remembers the pilot that flew into the sun and suggests that they may be sensitive to intense light. Spock volunteers to be McCoy's test patient and the doctor bombards him with light beams so strong that the Vulcan is blinded. Too late, the doctor realizes that only ultraviolet light is needed to kill the creatures.

Kirk sets off ultraviolet satellite flares over the planet Deneva, freeing its people from the parasites. Fortunately, Spock's blindness is temporary, due to a second eyelid developed by Vulcans to protect their eyes from the harsh sun on planet Vulcan.

Catspaw

Stardate: 3018.2

On the planet Pyris VII, two beings known as Korob and Sylvia have been sent on a mission of conquest by their home world. Using a matter transmuter, they assume human form to welcome the Enterprise landing party.

When one member of the initial landing party returns to the ship dead, Kirk, Spock and McCoy beam down to find Scotty and Sulu transformed into mindless zombies. Sylvia and Korob appear as witch and warlock and use scare tactics to keep the officers from investigating the planet and their motives. Kirk, Spock and McCoy are taken prisoner and shown examples of Korob and Sylvia's "powers," which includes heating a small model of the Enterprise over a flame and having the heat transfer to the orbiting ship.

Sylvia takes an interest in Kirk and decides to abandon her original mission in order to learn about human feelings and experiences. When she finds out the captain is merely using her to gain an advantage, she becomes furious and retaliates.

Korob ultimately helps the crew to escape, but Sylvia turns into a giant black cat and crushes him. Kirk then uses Korob's wand transmuter to destroy Sylvia's source of power--her amulet--before smashing the wand. Their powers gone, the aliens revert to their true form--fragile blue creatures who quickly die in the planet's atmosphere. With their demise, Scotty and Sulu return to normal and the landing party beams back to the Enterprise.

Metamorphosis

Stardate: Unknown

Assistant Federation Commissioner Nancy Hedford has become ill while trying to stop a war on Epsilon Canaris III. The shuttlecraft Galileo is assigned to take her to the Enterprise, where she will receive treatment for the otherwise fatal Sakuro's disease.

En route, the shuttlecraft is pulled off course by a mysterious, cloud-like entity. Deposited safely on the planet Gamma Canaris N, Kirk and his party meet Zefram Cochrane, the scientist that discovered warp drive over 100 years before. But Cochrane appears young and vital, despite his age. The cloud-like creature, whom Cochrane calls the "Companion," has kept him young and handsome over the years. The Companion captured the Galileo in order to give Cochrane human companionship.

The Companion prevents Spock from repairing the disabled shuttlecraft and Kirk is worried that Nancy Hedford will die before they can get her to the Enterprise for treatment.

By using a translating device, Kirk discovers that the cloud entity has a female personality and is in love with Cochrane, who doesn't care for that idea at all. He's fallen in love with Nancy Hedford and agrees to help destroy the cloud creature so that they can save Nancy's life. When that attempt fails, the cloud creature enters Nancy's body, saving her life, healing her. In this way, the Companion can know human love with Cochrane and Nancy Hedford's life can be saved. With the Companion no longer holding him on the planet, Cochrane is free to leave, but decides to remain with what is now Nancy/Companion. As the landing party departs, Cochrane and his new mate contemplate children and a normal life span.

Friday's Child

Stardate: 3497.2

Sent to the planet Capella IV to negotiate a mining treaty, Kirk and a party beam to the surface. They find the Capellans to be warlike and tradition-bound people. Kirk also finds that a Klingon agent, Kras, has gotten there before them and established an agreement with some of the planet's rebels who kill their leader, Akaar, and take over. Akaar's widow, Eleen, is willing to forfeit her life, as custom demands, because she carries the child that will be the next leader, or Teer.

Kirk convinces her to escape and they hide in the hills beyond the city. While the landing party evades pursuit, a Klingon warbird prevents the Enterprise from helping its people.

When Eleen goes into labor, McCoy delivers the child. Eleen, however, hits the doctor over the head with a rock, knocking him out, and returns to the Capellans. She tells them that the landing party and the child are dead. The Klingon decides this is the time to take control and begins to attack the Capellans.

Arriving on the scene, Kirk and Spock try to use primitive bows and arrows on the Klingons which wound, but do not stop. Maab, the new Teer, draws the Klingon fire while his lieutenant kills him. Eleen names her son Leonard James Akaar, after Kirk and McCoy, and as her son's regent until he comes of age, signs the mining treaty with the Federation.

Who Mourns for Adonais?

Stardate: 3468.1

As the Enterprise nears the planet Pollux IV, a huge, green hand made of energy materializes in space, catching the Enterprise and holding it captive. Kirk and a landing party are transported to the planet's surface where they find a being who claims to be Apollo, the last of the Greek gods who dwelled on ancient Earth's Mount Olympus. All the other gods, Apollo tells Kirk, died of loneliness when they left their home of Mount Olympus. Apollo's plan for the Enterprise crew is that they settle on Pollux IV and worship their god, Apollo.

Sensors show that Apollo's god-like abilities come from an organic ability to use energy from sources outside himself. His apparent powers include storms, thunderbolts and an ability to grow into a giant, towering above the Enterprise landing party.

Attempts to foil Apollo's plans are hampered by Lieutenant Carolyn Palamas, who has fallen in love with the god and whom Apollo decides will be his bride. Scotty, who has beamed down with the party, had harbored hopes of romance with the young lieutenant and objects to Apollo's attentions. Apollo's response is to hurtle the engineer through the air by way of a thunderbolt.

Spock determines that the god's powers come from his temple. When Kirk tells Lt. Palamas to reject Apollo, which she reluctantly does, the captain uses the Enterprise's weapons to destroy Apollo's temple. Apollo, rejected by a mortal woman and bereft of his powers, spreads himself upon the winds to join his fellow gods.

Amok Time

Stardate: 3372.7

When Spock begins to exhibit strange, erratic behavior, Kirk asks McCoy to conduct a medical examination. McCoy concludes that Spock is experiencing a potentially lethal internal distress.

Spock explains to them that Vulcans are married as children with the understanding that they will fulfill this commitment when they become adults. Spock has reached this time, the "pon farr," and if he doesn't get to Vulcan immediately to mate with his bride, T'Pring, he will die. Kirk jeopardizes his career by disobeying a direct order to the contrary from Starfleet, and proceeds with all possible speed to Vulcan. As Spock's friends, Kirk and McCoy are invited to witness the marriage ritual--the "Koon-ut-kal-if-fee." T'Pau, a highly respected member of the high-counsel, will conduct the ceremony.

Trouble starts when T'Pring announces she would rather marry Stonn, a full Vulcan. T'Pring evokes her right to have Spock fight for her. However, she chooses Kirk as her champion. Fearing his friend is too weak to fight, Kirk agrees. It is only then he is informed that it is to be a fight to the death.

The fight ensues and Spock quickly demonstrates physical superiority. McCoy objects to T'Pau that Kirk isn't used to the Vulcan atmosphere and climate. He asks to inject the captain with a tri-ox compound to compensate. T'Pau agrees and Kirk is given the injection.

During the fight, Spock kills Kirk and McCoy accompanies the captain's body back to the Enterprise. Spock, his mating urges curbed by the knowledge that Kirk, his friend and captain, is dead by his own hand, relinquishes T'Pring to Stonn. He solemnly returns to the starship. There he finds Kirk alive and well, having been injected not with tri-ox, but with a knock-out drug which simulated the signs of death. Overjoyed, Spock smiles and utters a delighted "Jim!" before returning to his controlled, logical self.

The Doomsday Machine

Stardate: 4202.9

Sent to investigate the destruction of several planetary systems, the Enterprise discovers a crippled starship, the Constellation, floating in space. Commodore Matthew Decker is the only one left on the ship. Kirk and Scotty remain on board the Constellation to try and repair the starship, while McCoy beams Decker aboard the Enterprise.

Decker informs the crew that a giant robot ship, a planet-eating machine made by a long-dead alien race, is roaming the galaxies, consuming all in its path for fuel, including whole planets. When Decker challenged it, the "berserker," as he calls it, attacked. Decker beamed his entire crew to the planet's surface below, only to have the robot consume that planet, killing the Constellation's entire crew.

When the "berserker" returns, Decker, consumed with guilt over the loss of his crew, pulls rank on Spock and takes control of the Enterprise. He seems determined to destroy the machine, even at the cost of another ship and crew. Kirk, still on board the Constellation, contacts Spock and supports his claim that Decker is exhibiting suicidal behavior and is therefore unfit to command. Thwarted, Decker steals a shuttlecraft and flies it down the 'throat' of the giant robot ship, killing himself.

Realizing that Decker's idea, on a larger scale, might work, he sets the Constellation to self-destruct and send it after Decker's shuttlecraft. Due to a transporter glitch, Kirk barely makes it back to the Enterprise before the Constellation explodes, destroying the planet killer in its path.

Wolf in the Fold

Stardate: 3614.9

Kirk and McCoy decide to take Scotty, who is recovering from a head wound accidentally caused by a female crew member, to a nightclub on the planet Argelius II. Scotty becomes infatuated with a lovely dancer at the club and they leave together. In the meantime, Kirk and McCoy decide to sample some of the planet's other pleasures and leave.

A scream sends them to a foggy alley to find the dancer dead with Scotty holding a bloody knife. McCoy suggests that perhaps Scotty's subconscious distrust of women since his accident has manifested itself in murder.

Hengist, the local authority, wants to arrest Scotty, but Kirk intervenes and seeks the help of a priestess of an old psionic cult. Unfortunately, she's killed and once more the blame seems to fall at Scotty's feet. Before she dies, the priestess says that something with an insatiable hunger and hatred of women is present in the room. Scotty still claims to have amnesia during the time when the women were killed.

In the end, the entity turns out to be an ancient life form, Redjac, previously known on Earth as Jack the Ripper. It now appears in true form: a noncorporeal vampire who thrives on others' fear. It preys on women because they are more easily frightened. It has been living in the body of Hengist and, when discovered, kills Hengist and flees to the Enterprise.

McCoy administers tranquilizers to everyone on board so that the creature cannot evoke fear. Enraged, it is forced to return to Hengist's body. Kirk, knowing this would happen, beams it into space at maximum dispersal, where it will die for lack of nourishment.

The Changeling

Stardate: 3451.9

The Enterprise is sent to investigate the destruction of the Malurian system and its four billion inhabitants. When it arrives at the coordinates, the starship itself is threatened by a space going, self-contained computer/probe calling itself Nomad. When Kirk identifies himself by name, Nomad mistakes him for "The Kirk," and thinks him to be his creator.

Nomad is beamed aboard the Enterprise and promptly erases Uhura's memory and kills Scotty, claiming that neither life form was perfect. At Kirk's demand Nomad repairs "the unit Scott," bringing him back to life.

Spock attempts a Vulcan mind meld with Nomad and learns that it was created on Earth in the twenty-first century by scientist Jackson Roykirk. Nomad's program was to seek out new life and report back to Earth. Damaged in space by a meteor, Nomad drifted until it found Tan Ru, an alien probe designed to sterilize soil. Using their self-repair systems, the two probes combined themselves into one. Nomad's programming was damaged and by joining with Tan Ru's now believes its mission is to seek out life and destroy anything that it does not believe perfect.

Kirk convinces Nomad that it had mistaken him, Captain James T. Kirk, for Nomad's creator, Jackson Roykirk, thus making Nomad imperfect and a candidate for "sterilization." A confused Nomad begins to self-destruct, exploding just after Kirk beams the changeling into space. Kirk checks on Uhura's progress after the attack by Nomad. McCoy informs him that her brain is undamaged and she must simply "relearn" what the probe erased.

The Apple

Stardate: 3715.3

When a landing party beams down to the planet Gamma Trianguli VI, they find what appears to be an idyllic paradise. They quickly discover, however, that the planet is deadly, sporting plants that shoot thorns, rocks that explode, and incredibly accurate lightning bolts.

With a much reduced party, they encounter the planet's inhabitants. They are a peaceful, child-like people who call themselves the "Feeders of Vaal." They dress in flowers and bright paint, never reproducing because they don't age or die. Each day they "feed" Vaal offerings of food. Vaal seems to be a large serpent's head carved of rock, but is actually the terminal for an advanced, underground computer. Seeing Kirk and his party as a threat, Vaal takes them prisoner and tries to pull the Enterprise from orbit.

Kirk realizes that by depriving Vaal of the natives' daily offerings of food, the computer won't be able to convert the offerings into reaction mass. Thus weakened, Kirk uses the Enterprise's phasers to destroy Vaal. This leaves the natives on their own to discover birth, death, and the everyday ways of life.

Mirror, Mirror

Stardate: Unknown

Caught in the beginnings of an ion storm, Kirk, McCoy and Uhura interrupt their negotiations with the Halkans for dilithium crystals, to return to the Enterprise. Scotty beams the landing party aboard as a burst from the storm hits the starship. The transporter malfunctions, sending Kirk, McCoy, Scotty and Uhura into an alternate universe. In this world, they soon discover the "Galactic Empire" is maintained by fear and assassination. Now, aboard the Imperial Starship Enterprise, the four must find a way to remain undetected until they can return to their own universe.

Meanwhile, the parallel versions of Kirk, Scott, McCoy and Uhura have been beamed on board the positive Enterprise. Their behavior is so different from their counterparts that Spock immediately realizes something is wrong. He had the four imprisoned until the transporter could be checked and repaired.

On the I.S.S. Enterprise, the parallel Chekov is foiled in an attempt to assassinate Kirk. When Kirk refuses to give an order to destroy the Halkans, who have refused to give up their dilithium crystals, the parallel Spock becomes suspicious.

The Imperial Fleet sends a secret message to the parallel Spock, telling him to kill Captain Kirk and assume command of the starship. Finding an unexpected ally in the parallel Spock, Kirk continues to stall while his three comrades gather the information needed to send them back to their own universe.

Parallel Spock has no desire to become captain, and therefore a mark for assassination. Along with Lieutenant Marlena Moreau, who wants the parallel Kirk back because she is "the Captain's woman," they help return the four Enterprise officers to their own world. Before he goes, Kirk talks to the bearded Spock, telling him the advantages of a Federation-like system over the anarchy of this universe. Spock seems almost convinced that he should in fact get rid of his Kirk, seize control of the I.S.S. Enterprise, and manipulate the Imperial Starfleet into working toward a more civilized universe.

The Deadly Years

Stardate: 3478.2

On the way to Starbase 10, the Enterprise stops to deliver supplies to the colonists of Gamma Hydra IV. A landing party consisting of Kirk, Spock, McCoy, Scott, Lieutenant Galway and Chekov beam to the planet's surface. They find that accelerated aging has taken place, killing most of the colonists. Chekov is terrified when he discovers the first body. The only survivors, an elderly couple who claim to be in their twenties, die shortly after meeting the Enterprise crew. When the landing party returns to the Enterprise, the aging acceleration begins to affect each of them ... except Chekov, who remains curiously immune. While Kirk wants to stay in orbit around Gamma Hydra IV until a cure can be found, one of his passengers, Commodore Stocker, wants to proceed to Starbase 10 where he feels the best medical aid can be obtained.

The senior officers succumb to the effects of old age and soon Kirk is unable to command, as are Scotty and Spock. Command falls to Commodore Stocker, who, while an efficient desk officer, has no deep space training. Thinking he will save time, Stocker plots a course through the Romulan Neutral Zone on his way to Starbase 10. The Romulans are waiting and begin an attack.

Stocker, panicked and inexperienced, has no idea what to do. As the Enterprise is surrounded, McCoy comes up with an antidote to the aging sickness ... adrenaline. Chekov, he explains, wasn't affected because his fear at finding the bodies on Gamma Hydra IV had already kicked his natural adrenaline into high gear.

McCoy restores Kirk to normal in time to save the ship by reusing his famous "corbomite" bluff and telling the Romulans that the Enterprise would destroy anything within a 200,000 kilometer radius. McCoy distributes the antidote and restores everyone to their normal state.

I, Mudd

Stardate: 4513.3

Norman, an android pretending to be a member of the Enterprise crew, takes control of the starship and her crew, taking them to an unnamed planet where Kirk discovers an old nemesis ... Harry Mudd.

Fleeing from his most recent criminal exploit, Harry crash-landed on the planet, which is inhabited by androids designed by a long-extinct race. At first their desire to fulfill his every need seemed like paradise, but Harry soon realized that precluded him ever leaving the planet. So, sending Norman to capture the Enterprise, Mudd hoped to trade the starship's crew for his own freedom.

The androids, however, want to use the Enterprise as a vehicle to populate the universe, serving mankind and protecting them from themselves. Unwilling to spend their lives on the strange planet, waited on by machines, Kirk and company set about finding a way out. It is not without temptation, however.

Spock is shown what is supposedly the control center for all the androids ... a veritable electronics dream come true. McCoy is given an extensive lab, set up to do all the research he's ever wanted to do, while Scotty is shown the technical machine shop of his dreams. The androids offer Uhura eternal youth and beauty while Chekov contemplates a planet filled with beautiful young women.

In the end, however, the crew bands together in an attempt to thoroughly confuse and, ultimately, short-circuit them. Through a series of illogical and very funny antics, the Enterprise crew and Mudd cause Norman, the central control for all the androids, to have an electronic "nervous breakdown."

Instead of granting Harry Mudd his freedom, Kirk leaves him on the planet with the remaining androids ... including many fashioned in the image of his shrewish wife, Stella, until he mends his ways.

The Trouble With Tribbles

Stardate: 4523.3

When the Enterprise receives a top-priority order to protect a shipment of quadrotriticale grain on Deep Space Station K-7, Kirk is irritated to be guarding a shipment of "wheat." But the shipment is meant for famine-struck Sherman's Planet, and Klingons are taking shore leave on the space station. Adding to Kirk's irritation is Federation Undersecretary for Agriculture, Nilz Baris, and his pesty assistant, Arne Darvin, who inform Kirk that Starfleet Command is afraid the Klingons may try to steal the grain.

Another problem arises when a space trader, Cyrano Jones, gives Uhura a purring ball of fluff known as a tribble. Charmed by the creature, Uhura takes it back to the Enterprise. However, as McCoy soon learns, tribbles are born pregnant and the more they eat--and they eat constantly--the more they multiply. Soon the starship is overrun by the furry creatures.

Kirk soon finds that the bins that were once full of the precious quadrotriticale are now full of dead tribbles. The grain has been poisoned by a Klingon agent disguised as the Undersecretary's assistant, Darvin. His true identity is exposed when Kirk discovers that tribbles don't like Klingons (and vice-versa) and squeak whenever they're in near proximity. The Klingons leave the space station and Scotty rids the Enterprise of the tribbles by beaming them aboard the departing Klingon ship where, as he tells Kirk, " ... they'll be no tribble at all."

Bread and Circuses

Stardate: 4040.7

The Enterprise finds the wreckage of theS.S. Beagle, with no survivors, orbiting near the Planet 892-IV. When Kirk, Spock, and McCoy beam to the planet's surface, they find a disheveled group of "sun worshipers" trying to escape being caught by the local authorities. They are captured, along with the landing party, and taken to the city which looks very much like Earth's ancient Rome.

They find that Captain R.M. Merrick of the Beagle has betrayed his crew, beaming them down to fight in the Roman-like gladiatorial games. Merik is First Citizen of the Empire and supposed close friend to the Proconsul, Claudius Marcus. Kirk realizes, however, that Merrick is being used as a lure to get more starship crews to 892-IV for the entertainment of its inhabitants.

When Kirk refuses to beam his crew down to die in the arena, Spock and McCoy are condemned to fight gladiators in the ring. The bout is being televised for the planet's enjoyment, but Scotty cuts off the planet's energy supply, spoiling their pleasure. When Kirk uses the confusion to free Spock and McCoy, Merrick sees how a true starship captain acts in the face of danger and uses his communicator to have Kirk, Spock and McCoy beamed aboard the Enterprise. For his treachery, Merrick is killed by the Proconsul.

Uhura, who has been monitoring the radio waves of the planet, realizes that the "sun worshipers" aren't talking about the sun in the sky, but of the "Son of God."

Journey to Babel

Stardate: 3842.3

The Enterprise is appointed to transport ambassadors from many worlds to the Babel Conferences. Among those aboard are Ambassador Sarek of Vulcan and his human wife, Amanda--Spock's parents.

Keeping peace aboard his ship is complicated for Kirk by an unidentified vessel following the Enterprise and high tensions running among delegates on board. At a cocktail party, Ambassador Gav, a Tellarite, quarrels openly with Sarek about the admission of Coridan into the Federation. When Gav is later murdered, circumstantial evidence points to Sarek. The strain of such an accusation causes Sarek's already existing heart condition to worsen and he has the Vulcan equivalent of a heart attack. McCoy battles with less familiar Vulcan physiology to try and correct the damage. Spock is needed as a blood donor for the operation.

When Kirk is attacked by Thelev, an Andorian, Spock assumes command of the Enterprise, and refuses to participate in McCoy's operation on his father. The Vulcan insists that they identify and stop the vessel that is following them. Kirk fakes recovery and returns to the bridge, freeing Spock to go to the sickbay and assist in his father's surgery. On the bridge, Kirk must deal with the unknown ship, now in contact with someone on board the Enterprise. A search uncovers the fact that Thelev is not Andorian, but a surgically altered Orion, put on board to disrupt the Babel Conference.

The unknown ship attacks the Enterprise and is defeated. Rather than be captured, it destroys itself and Thelev commits suicide. With Spock available for the blood transfusion, Sarek's operation is a success and he recovers. Father and son make peace, realizing they have a common bond that transcends their differences. Kirk returns to sickbay for treatment of the knife wound caused by Thelev and McCoy gets the last word.

A Private Little War

Stardate: 4211.4

Captain Kirk leads a survey mission to a peaceful, primitive planet which he visited 13 years before as a lieutenant. He is dismayed to see a group of villagers armed with flintlocks, weapons they shouldn't have at their current stage of development. The villagers ambush the landing party and wound Spock. Returning to the Enterprise, Spock is put under the care of Dr. M'Benga, who once interned in a Vulcan ward. M'Benga tells McCoy they've done all they can for Spock, and that he has to recover on his own.

Meanwhile, a Klingon vessel is detected in orbit around the planet, and Kirk orders Chekov to keep the Enterprise out of sensor range while he returns to the surface. He'll be looking for Tyree, the tribal leader he befriended years earlier. Minutes after Kirk and McCoy beam down in native clothing, they are attacked by a mugato, a white apelike creature with poisonous fangs, who bites Kirk before McCoy can kill it with a phaser. They can't return to the Enterprise, so Kirk tells McCoy that Tyree's people have a cure for the mugato poison.

Some hill people find Kirk and McCoy and take them to their caves, informing them that Tyree is now their leader, and his wife, Nona, knows how to help Kirk. But Tyree and Nona are currently on a scouting mission. Nona is using drugs to keep Tyree devoted to her, and she urges him to acquire "firesticks" for their people, but being a devoted pacifist, he refuses. Informed about Kirk, Nona heads back to the caves, where she sees McCoy using his phaser to heat some rocks. Nona is intrigued, and wants to know more about their guests. Nona treats Kirk by cutting her hand and pressing a mahko root against Kirk's wound. She collapses but Kirk recovers. Now, according to legend, Kirk will be unable to refuse Nona anything.

Meanwhile, on the Enterprise, Dr. M'Benga has informed Nurse Chapel that Spock is in a state of self-induced hypnosis to heal his own injuries. When Spock's readings fluctuate, M'Benga is pleased, and tells Chapel that if Spock regains consciousness she is to do whatever the Vulcan asks.

Tyree tells Kirk and McCoy that the firesticks first appeared nearly a year ago, but assumes the villagers have been making them--he hasn't seen any strangers. Kirk asks him to take them to the village under cover of dark. Nona joins them and implores Kirk to help make Tyree a powerful man, but the captain says he will not interfere.

Tyree leads Kirk and McCoy into the village, where they find a forge containing clear evidence that Klingons are involved. They watch in hiding as the villager's leader, Apella, enters with a Klingon. Kirk and McCoy overpower them, take a flintlock and escape with Tyree's help.

Spock regains partial consciousness and demands that Chapel strike him. She does so hesitantly at first, but at Spock's insistence she slaps him harder and harder, until Scotty walks in and stops her, not knowing he's endangering Spock by doing this. M'Benga finds out what's happening, rushes over and slaps Spock violently until he is fully conscious. Spock thanks him for bringing him out of his hypnotic state.

On the planet, Kirk teaches Tyree and his people how to fire the stolen flintlock. McCoy points out that he is corrupting the hill people's society, but Kirk replies that the Klingons left them no choice--in order to bring equity back between the hill people and the villagers, he has to provide equal weapons. McCoy is horrified, but has no alternative solution. Realizing Tyree is hesitant to arm his people, Kirk hopes that Nona can convince her husband to fight. When he approaches her, she uses the same drug on him that she used to seduce Tyree. Kirk falls under her spell. Tyree sees what's happening and aims the flintlock at his wife, but he cannot bring himself to shoot. He throws the weapon away in disgust and walks off.

Suddenly, a mugato attacks Kirk and Nona. After a struggle, Kirk is forced to destroy the creature with his phaser. Seeing her opportunity, Nona knocks Kirk out and takes the phaser. Tyree and McCoy find Kirk and revive him, while Nona runs into a patrol of villagers and offers them victory by using Kirk's phaser. But the villagers attack and kill her. Tyree and Kirk rush in and overpower the villagers. When Tyree learns that Nona is dead he takes up the rifle and tells Kirk he needs more weapons. McCoy retrieves Kirk's phaser, and Spock contacts them from the ship. Kirk orders Scotty to manufacture a hundred flintlocks--they are making serpents for the Garden of Eden.

The Gamesters of Triskelion

Stardate: 3211.7

During a routine transport to a planet, Captain Kirk, Lieutenant Uhura and Ensign Chekov are intercepted and abducted by a powerful and distant transporter beam. Arriving, literally, flat on their backs on a planet called Triskelion in the M-24 Alpha star system, they are immediately attacked by beings from several different species, each of them wearing a collar around their necks.

Kirk and his crew mates have been brought to this planet to fight as gladiators in combat games in order to entertain and provide exciting gambling for the disembodied entities called the "Providers." Each assigned a "drill thrall" of their own, Kirk and his companions are collared as well, which asphyxiate those who are disobedient to the Providers.

On board the Enterprise, Spock, aware that the crew members are missing, attempts to locate them, and eventually finds the origin of the beam. Upon its arrival, the crew of the starship is also taken captive by the Providers.

With the ship and his entire crew at stake, Kirk makes a final wager to the Providers which they cannot resist: himself against three drill thralls on the condition that if he wins, all the drill thralls go free and are taught how to live for themselves again. If Kirk fails, he promises himself and the entire crew as the most entertaining fighters they've ever seen.

Kirk beats the three drill thralls and wins the wager, and the Providers set all the thralls free and permit the Enterprise and her crew to leave also.

Obsession

Stardate: 3619.2

Eleven years ago, the Farragut encountered a deadly cloud creature with vampire-like tendencies. James T. Kirk was on board the Farragut at that time as they entered the region of Tycho IV. The creature killed the ship's commander, Captain Garrovick, and half the crew by draining their red blood cells. To this day, Kirk feels guilt at having hesitated before firing at the creature--even though his phaser blast had no effect.

On his way to deliver necessary medical supplies, Kirk encounters what he believes is the same blood-sucking entity. He pursues it, against orders, determined to destroy it before it kills again.

A landing party beams down to the surface of Argus X, where the creature has taken refuge. In the party is the son of Kirk's former captain ... Ensign Garrovick. Garrovick spies the creature and, like Kirk 11 years before, hesitates before firing. The creature escapes and Kirk blames Garrovick for the resulting death of a crewman.

The creature leaves the planet with the Enterprise in pursuit. When Kirk fires on it, the creature turns and enters the starship. Fortunately, its first victim is Spock and, after tasting his copper-based Vulcan blood, flees toward its home world, Tycho IV. Fearing the creature will reproduce and, at the very least, kill others, Kirk and Garrovick prepare a trap with a matter/antimatter bomb and human blood. They lure the creature to take the bait and beam aboard the Enterprise as the creature is killed in the resulting explosion.

The Immunity Syndrome

Stardate: 4307.1

The Enterprise is en route to Starbase 6 for shore leave when Uhura receives a jumbled message from which all she can make out is a sector coordinate and the name Intrepid, a starship manned entirely by Vulcans. Suddenly, Spock shudders with pain and reports that the Intrepid just "died."

Kirk gets orders to head to Sector 39J because all contact has been lost with solar system Gamma 7A and with the Intrepid, which was investigating it. As the Enterprise changes course, long-range sensors show that the solar system, and its billions of people, are dead.

Approaching its destination, the Enterprise encounters a strange dark area in space. Kirk launches a probe. Seconds later, the crew hears a high-pitched whine throughout the ship, rendering half the people on board ill, and causing some to faint. Spock speculates that the phenomenon is some form of energy that is probably responsible for the death of the system inhabitants and the Intrepid crew. Kirk decides to move closer, and the crew hears the whine again. This time when they recover, the stars seem to have vanished. Spock reports that the noise was produced when the Enterprise passed through a boundary layer, and that they are surrounded by a field that is draining their mechanical and biological energy. McCoy confirms this when he reports from sickbay that everyone on the ship is dying.

Attempts by Scotty to recalibrate the engines and break free from the dark zone fail, and in fact the ship's expenditure of energy attracts an enormous amoeba-like creature approximately 18,000 kilometers in length. McCoy identifies the creature as an incredibly simple, single-celled organism which feeds on energy, but he needs more data to save the ship. He and Spock each volunteer to take a shuttle to investigate the creature--what would most certainly be a suicide mission--and Kirk decides to send Spock.

Spock takes the shuttlecraft through the creature's membrane and moves toward its nucleus. He reports that the creature appears to be ready to reproduce. He loses voice contact but manages to continue transmitting data.

Kirk and McCoy determine that if the creature begins to reproduce, it will spread rapidly and pose a serious threat to the galaxy, so it must be destroyed. But the Enterprise only has enough power left to survive for an hour.

Kirk and McCoy realize they have to use the Enterprise as an "antibody." Kirk orders the ship to punch its way into the giant creature and set a course for the nucleus. An antimatter charge is attached to a probe with a seven-minute delay. As soon as it is lodged in the nucleus, the Enterprise backs away at full impulse. There are only a few seconds to spare, but then they detect Spock's shuttle. Kirk locks two tractor beams onto the shuttle, even though doing so delays their escape. But when the antimatter explosion ruptures the creature's membrane, both ships are thrown to safety.

A Piece of the Action

Stardate: 4598

The planet Sigma Iotia II's last visit by the Federation was by the Horizon a hundred years before. Realizing the lapse in monitoring the planet, the Federation sends the Enterprise to observe the progress of Iotia's population.

Beaming down to the planet's surface, Kirk, Spock and McCoy are surprised to see a much different society--an Earth-like 1920s gangster culture--than was reported by the Horizon crew. Bodily seized, the landing crew are taken before one of the major planetary leaders, mobster Bela Oxmyx. Wishing to unite the population under his rule, Bela offers Kirk "a piece of the action" in exchange for the technologically advanced weapons of the Enterprise.

Meanwhile, the other lead gangster, Jojo Krako, has his own idea about being the head mobster and captures the Enterprise officers. Struggling to gain the upper hand in this comical power struggle, Kirk creates a diversion--a little card game known as fizzbin. Without knowing the nuances of the culture, Kirk and Spock try to accomplish their mission when Kirk attempts to drive a car and Spock strives to speak in gangster slang.

Finally, Bela Oxmyx is given a display of the Federation's power when he is beamed aboard the Enterprise and held hostage in the transporter room. Arranging a meeting between the two antagonists, Kirk is successful in uniting the two gangs in a loose system of government with the Federation as Godfather ... for a piece of the action, of course. Furthermore, upon discovering a book, "Chicago Mobs of the Twenties", the Horizon crew left behind 100 years before, Kirk and Spock finally understand how the highly imitative Iotians reinvented their entire society.

Back aboard the Enterprise, Kirk notices McCoy unusually drawn and worried. When questioned, McCoy is forced to admit that he thinks he left his communicator on Sigma Iotia II, leaving him to wonder what type of planetary society the next Federation visit will find ...

By Any Other Name

Stardate: 4657.5

When the Enterprise answers a distress call from a small planet, the landing party is captured by a group of agents from the Kelvan empire, located in the distant Andromeda galaxy. The Kelvans' purpose is to find planets suitable for colonization. However, their own ship was destroyed and now they need the Enterprise to make the 300-year journey home. To utilize the starship, the Kelvan--huge, tentacled creatures--take on human form. After several attempts at escape, Kirk accepts his fate and agrees to let the aliens take over his ship. The Kelvans use their technology to transform all but essential Enterprise personnel into small "cubes" which, unless broken or damaged, can be restored to human beings.

Recognizing that the Kelvans, in their new human bodies, are discovering human sensation and emotion, the remaining crew attempts to foster dissent amongst the aliens: Scotty succeeds in gettting one of them drunk, McCoy injects an irritant into another, and Kirk makes romantic overtures to the Kelvan leader's woman. With the Kelvans thus distracted, Kirk and the crew are able to regain control of the ship.

Kirk points out to Rojan, the Kelvan leader, that the Kelvans are already becoming less like they were before by encountering the humans. In 300 years, their descendants will be so human-like that they won't be able to live among their people on Kelva. Rojan sees the logic in his argument and sends a robot probe to Kelva, reporting what has happened. Pledging to restore the Enterprise crew, Rojan accepts Kirk's offer that the Enterprise find the Kelvans a Class-M planet to colonize.

Return to Tomorrow

Stardate: 4768.3

The Enterprise tracks a mysterious SOS to an ancient planet presumed long dead. The crew hears a voice from a telepathic being named Sargon, who asks Kirk to beam down to the surface. When Kirk, Spock and McCoy arrive in the transporter room, they find that Dr. Ann Mulhall has also been summoned. Sargon operates the transporter and leaves the security guards behind.

The landing party find themselves in a vault, and encounter a glowing sphere that identifies itself as Sargon. He explains that his people were destroyed in a cataclysmic war half a million years ago, and that he once had a body, but now is only pure thought. Sargon insists that he and two others of his kind need to "borrow" the bodies of the Enterprise officers long enough to construct new artificial ones. Sargon briefly takes control of Kirk's body, and leads the landing party into another chamber holding two rows of spheres, which are all now dark except for two. Those two beings are Sargon's wife, Thalassa, and his former enemy, Henoch. Sargon explains that this is how they stored their minds after the war, laying in wait for someone to find them. But by now Kirk's body is weakening, so Sargon returns control to the captain.

Scotty beams the three receptacles aboard and McCoy monitors the transfer process in Sickbay. Sargon takes Kirk's body, Thalassa takes Mulhall's, and Henoch takes Spock's. They are all overwhelmed by the pleasure of having physical bodies after so many years. Almost immediately, though, Henoch plots to kill Sargon in Kirk's body. While Sargon leads the effort to build androids for them to occupy, Henoch attempts to lure Thalassa into agreeing that they should keep their host bodies.

Henoch telepathically forces Nurse Chapel to poison Sargon (in Kirk's body) and then destroys the globe that houses Spock's mind. McCoy and Nurse Chapel keep Kirk's body on life support, but his mind is still trapped in Sargon's receptacle. Henoch has completed an artificial body for Thalassa, but she refuses to transfer her consciousness into it. Instead, she goes to sickbay and offers McCoy a chance to save Kirk in return for keeping the human body. McCoy refuses, so she attacks him with her thoughts. But then she realizes what she's doing and breaks off her assault. Suddenly, she and McCoy hear Sargon's voice: he transferred his mind into the ship's computer, and he has a plan. Chapel arrives, and Thalassa orders McCoy out of the room. The room shakes, and a few seconds later Chapel walks out. When McCoy rushes back in, he finds Kirk and Mulhall restored to normal, and all the receptacles destroyed. Kirk orders McCoy to prepare a hypo with a deadly injection: Spock's mind is now dead, so now they must destroy Henoch.

By now Henoch has taken control of the Enterprise. On the bridge, McCoy attempts to inject him, but Henoch stops him and orders Nurse Chapel to inject the Doctor. She takes the hypo, but injects Spock's body instead. Henoch tries to move to another body, but Sargon stops him, and he falls to the floor. Chapel staggers, and Spock stands up. It turns out that Spock's consciousness had been transferred into Chapel's body, and that the injection wasn't really deadly--Sargon had manipulated the Doctor to believe it was because Henoch could read McCoy's thoughts.

Sargon and Thalassa realize that they cannot live in the physical world, but before they depart to roam the universe in their noncorporeal state, they inhabit Kirk's and Mulhall's bodies one last time so they can share a kiss.

Patterns of Force

Stardate: 2534

The Enterprise is sent to planet Ekos to investigate the disappearance of an old Academy professor of Kirk's--historian John Gill. The Enterprise is attacked by an armed probe with a thermonuclear warhead, technology that is too advanced to be from Ekos or the nearby Zeon. Captain Kirk destroys the probe before it can do any damage, then takes the ship into orbit around Ekos out of range of the planet's detection devices. Spock tells him that, according to their records, the Ekosians are primitive, warlike people in a state of anarchy; Zeon has a relatively high level of technology, and its people are peaceful.

Kirk decides to beam down to Ekos with Spock; and Dr. McCoy fits them both with subcutaneous transponders. Scotty is ordered to use the transponders to locate and beam them back if they fail to make contact in three hours. When Kirk and Spock arrive on the planet's surface, a Zeon man urges them to hide. They watch as the man is arrested by officers wearing swastika armbands. Spock reminds Kirk that the Prime Directive prohibits them from interfering.

A viewscreen in the street plays news footage revealing that Ekos has adopted a military regime similar to that of Nazi Germany, and is now at war with Zeon. Kirk is puzzled that another planet could independently develop a culture identical to one that once existed on Earth. They watch a female Nazi officer called Daras receive a medal of honor, and learn that the planet is committed to the death of Zeon. The broadcast ends with a salute to the F�hrer, John Gill.

Kirk and Spock steal uniforms and assume the identities of Nazi officers in order to infiltrate government headquarters, but they are arrested before they can find Gill. Their phasers and communicators are confiscated, and they are tortured and interrogated. In jail they meet Isak, the man they saw being arrested earlier. Isak tells them that the Nazi movement on Ekos began when Gill arrived a few years earlier, and it is only a matter of time before Ekos invades Zeon.

Spock uses his subcutaneous transponder to make a crude laser that cuts open the cell door. They find their communicators in pieces, but Spock takes one and they escape. Isak takes Kirk and Spock to an underground resistance group led by his brother Abrom. Kirk explains to Abrom that he needs to find John Gill in order to end the war. But then the resistance cell is infiltrated by Daras, the high-ranking Nazi woman seen in the newsreel, who shoots Abrom. Kirk and Spock overpower and disarm her, but then they learn Daras is really a member of the underground, and the shooting was a ruse to test their loyalty. Isak and Daras explain that Deputy F�hrer Melakon is the one in command. Gill sees no one, but he is making a speech from the Chancellery. Daras agrees to help Kirk, Spock and Isak get past the guards. They dress as members of a Gestapo film crew and make their way into the headquarters. Isak wants Kirk and Spock to kill Gill as soon as possible, but Kirk refuses.

They find Gill in a booth surrounded by guards. Spock observes that he seems to be ill, or perhaps drugged. When Spock contacts the Enterprise with a repaired communicator, Kirk tells McCoy to put on a Nazi uniform and beam down. Watching Gill make his speech, McCoy confirms that he has been heavily drugged. Kirk, Spock and Isak overpower the guards so that McCoy can administer a stimulant to Gill, but he fails to revive him. Spock performs a mind probe on Gill, which brings him to consciousness. Gill tells them he used the example of Nazi Germany to bring order to Ekos. It worked at first, but then Melakon seized control, drugged Gill to use him as a figurehead, and started the war with Zeon. With another, potentially fatal dose of stimulant, Kirk keeps Gill conscious so he can make another broadcast from the booth. Gill announces that he has recalled the fleet and that the war must stop; he also tells the people that Melakon is a traitor. Melakon opens fire on the booth, and Isak shoots him. Gill is fatally wounded, but before he dies, he tells Kirk he was wrong to break the Prime Directive. But now he hopes the damage has been undone, and the Ekosians and Zeons will now work together.

The Ultimate Computer

Stardate: 4729.4

The Enterprise is chosen to be the test ship for the new M-5 multitronic computer system, a computer meant to be able to run a starship without human intervention. Also aboard for the test is Dr. Richard Daystrom, the inventor of the M-5 and an obsessive and unstable individual.

Initially the M-5 performs well, but when it decides to destroy a robot freighter, Kirk orders the test canceled. The M-5, however, protects itself and makes it impossible for it to be disconnected. The computer becomes increasingly erratic, a result of Dr. Daystrom's decision to impress his engram onto the computer as part of its programming. Starting a scheduled war games drill, M-5 uses the full arsenal of the Enterprise to attack four other Federation starships.

In a last-ditch appeal to the M-5, Kirk makes the computer realize that it has committed the sin of murder. Since Dr. Daystrom would be ethically abhorred at such an act, the M-5 is equally penitent and tries to commit suicide by leaving the Enterprise defenseless against a counter-attack by the remaining other starships. At the last moment, Spock and Scott are able to finish disconnecting the M-5 unit. Kirk keeps the shields down, gambling successfully that the attacking ships would not fire on an undefended vessel. Restoring communications next, the fleet is called off.

The Omega Glory

Stardate: Unknown

The Enterprise finds a crewless starship, the Exeter, in orbit around the planet Omega IV. The boarding party from the Enterprise contracts a virus that may have killed the Exeter's crew, but the biosphere on Omega IV is found to contain an immunity. The party is beamed to the surface.

There they discover Captain Tracey, the commander of the Exeter. He has been violating the Federation's Prime Directive by interfering in the politics of the natives, using his phaser to protect the asian-like villagers, the Kohms, against the barbarian raiders, the Yangs. Tracey demands that Kirk supply him with more phasers, which Kirk refuses to do.

The Yangs capture the Kohms village and the Enterprise crew learns that these people are possibly descendants of Earth's Communist Chinese who left Earth in the last years of the 20th Century. The Yangs mouth a distorted version of the United States Constitution, which are their 'holy words' and which Kirk recites, gaining their confidence. Prolonged exposure to the planet's atmosphere cures the landing party and, with Captain Tracey under arrest, they return to the Enterprise.

Assignment: Earth

Stardate: Unknown

Sent back in time to find out how Earth managed to survive without destroying itself, the Enterprise inadvertently beams aboard a space traveler, Gary Seven, along with his black cat, Isis. Seven claims to be a 20th-century human raised and trained by unknown and unnamed aliens to prevent Earth from destroying itself. Before Kirk can determine whether or not the man is telling the truth, Seven escapes to the planet below. Kirk and Spock follow him to Earth. Meanwhile, Seven has tried to contact two fellow agents, who are discovered to have recently died in an auto accident. Instead, he contacts Roberta Lincoln, who becomes his reluctant cohort.

An orbital bomb is about to be launched by the United States and it is Seven's mission to make sure the rocket explodes somewhere over Asia, thereby frightening the governments into not launching future bombs into space.

When the rocket goes out of control, Seven barely succeeds in stopping it, despite Kirk and Spock's well-meaning interference. Before Kirk and Spock leave Earth, Kirk consults the Enterprise's computer records and informs Seven and Roberta that they have a very interesting future in the offing.

Spectre of the Gun

Stardate: 4385.3

Kirk ignores an alien buoy that warns the Enterprise that it is trespassing into Melkotian space and continues forward when the Melkots transport Kirk, Spock, McCoy, Scotty, and Chekov to a recreation of Earth's wild west. Here their instruments will not function and they are forced to relive, in "a manner befitting their heritage for trespassing," the shoot-out in Tombstone, Arizona on October 26, 1881.

The Enterprise party is transported to the OK Corral, but as they will not fire on the "Earps," the gunfighters cannot hurt them. Chekov, in the role of Billy Claiborne, is killed and Spock realizes that these events are not really transpiring. Through a series of mind melds, Spock is able to reject the illusions of the hostiles enabling the crew to succeed without shooting at the others. The Melkots are impressed by the peaceful behavior of the Enterprise party and return them, including Chekov, who had been killed in an earlier altercation, to the Enterprise. The Melkots agree to establish contact with the Federation.

Elaan of Troyius

Stardate: 4372.5

Two United Federation of Planets members, Elas and Troyius, suffered war for centuries. With Klingon Empire expansion approaching the planets' system, Tellun, the Federation sends the Enterprise to lend assistance in a peace negotiation. The peace treaty is to be completed by the bonding in marriage of the two planets' leaders, the Dohlman of Elas and the leader of Troyius. The starship provides transport for the Dohlman to Troyius, while also offering a time and place for the Dohlman to learn the duties and customs of Troyius.

Upon her arrival on the Enterprise, it is clear that the Dohlman, Elaan, is an arrogant and reluctant bride. Ambassador Petri from Troyius attempts to educate Elaan in preparation of her wedding, but is rewarded with a knife wound. Captain Kirk must step in as Elaan's tutor to insure that the alliance takes place. Kirk takes a strong hand in Elaan's education, but his efforts are compromised when she begins to cry and he touches one of her tears. The Elasian tears of a Dohlman carry an infectious agent which acts as a powerful aphrodisiac.

While the captain fights the effects of Elaan's tears, a Klingon battlecruiser appears. In the ensuing melee, it is apparent that the Klingon captain is attempting to lure the starship into warp speed which, as Scotty soon discovers, would destroy the ship. A saboteur from the Elasian party has damaged the dilithium crystal chamber, rendering the crystal inert, and the ship nearly powerless.

While under attack, Spock detects strong energy readings which emanate from a crystal necklace of Elaan's, made of dilithium. Fitting the raw crystals into the anti-matter chamber, the ship is able to fend off the Klingons and continue to Troyius. Kirk and McCoy discover the one true cure for the Elasian tears--prior infection--in Kirk's case, the starship Enterprise had infected him even more powerfully than had the Dohlman.

The Paradise Syndrome

Stardate: 4842.6

Investigating a planet in danger of collision with an asteroid, Captain Kirk, Mr. Spock, and Dr. McCoy discover both Native American inhabitants and a strange alien obelisk. While examining the obelisk, Kirk is accidentally trapped inside. Trying to escape, he inadvertently triggers a device that gives him amnesia.

Unable to locate the Captain, Spock and McCoy return to the Enterprise to try and stop the asteroid from hitting the planet.

Now free from the obelisk, Kirk is found by the natives, who come to believe Kirk (calling himself Kirok with his damaged memory) is a god. Kirk both becomes the tribe's medicine chief and marries the priestess Miramanee.

Meanwhile, the Enterprise fails in its attempt to destroy the asteroid. Spock is able, however, to translate the obelisk's carvings. He learns that an alien race known as the Preservers transplanted the Indians to this world, and provided an asteroid deflector inside the obelisk to protect them.

Returning to planetary orbit, Spock and McCoy beam down. They find the natives, frightened that Kirk does not know how to use the obelisk to protect them, stoning Kirk and Miramanee. Rescuing the pair and restoring Kirk's memory, Kirk and Spock enter the obelisk and activate the deflector. The planet is saved but Miramanee, pregnant with Kirk's child, dies from her injuries.

The Enterprise Incident

Stardate: 5027.3

Seeming tense and erratic, Captain Kirk takes the Enterprise into Romulan space and the ship is immediately surrounded by Romulan warships. Kirk and Spock beam aboard the Romulan flag-ship and confront the Romulan Commander, a woman. Kirk explains that his ship entered Romulan territory because of equipment malfunction. Spock, however, denounces this explanation, saying Kirk ordered them here, due to his reduced mental stability. This, not surprisingly, enrages the Captain. The Romulan Commander orders the Enterprise be taken to the Romulan base. Scotty, placed in command of the starship, refuses. McCoy is beamed aboard the flag-ship to tend Kirk, who has become irrational to the point of violence. When he arrives, Kirk attacks Spock who reacts, without thinking, by using the Vulcan death grip, killing Kirk.

McCoy returns to the Enterprise with Kirk's body, while Spock remains on the Romulan ship. Unknown to the Romulan Commander, this has all been a ploy to sneak the officers on board and steal the Romulan cloaking device. After Kirk's body has been removed to his ship, the Romulan Commander begins to try and entice Spock into defecting to the Romulan side.

Disguised as a Romulan, Kirk returns to the Romulan ship and steals the vessel's cloaking device and returns with it to the Enterprise. When the Commander discovers the theft, she feels betrayed and in retaliation decides to execute Spock. The Vulcan pretends to confess to her and ultimately stalls until Scotty is able to install the cloaking device on board the Enterprise. Spock is beamed back aboard the starship, but since the Romulan Commander was standing near him, she is also beamed aboard.

The Romulan Subcommander, now in charge of the flag-ship, gives chase, ordered by his commander to destroy the Federation ship. Fortunately, the newly-installed cloaking device works and the Enterprise makes good her escape, with the Romulan Commander on board a their prisoner.

And the Children Shall Lead

Stardate: 5029.5

When the Enterprise finds that all the adults in the Starnes Expedition to Triacus have killed themselves, they beam to the planet's surface to investigate. The children, however, are alive and well and strangely oblivious to their parents' fates.

They are beamed aboard the Enterprise while Kirk searches for an answer to the strange occurrences. The children summon their "friendly angel" Gorgan, who tells them to take the Enterprise to a planet he can control. By garbling Kirk's words and deceiving Spock, the children are able to take control of the starship. Finally, seeing Kirk's anxiety at the loss of his ship, Spock realizes that something is wrong and helps the Captain regain control.

Kirk shows the children tricorder tapes of their parents ... and their graves, demonstrating to them that Gorgan is not a "friendly angel" but an evil force. The loss of his believers renders Gorgan impotent and he fades into oblivion.

Spock's Brain

Stardate: 5431.4

The Enterprise is on a routine mission in deep space when a beautiful young woman beams onto the bridge. Without a word, she touches a band on her wrist and everyone is rendered unconscious. She moves around the bridge until finally she comes to Spock. Smiling, she lays a hand on the Vulcan's head, as if she's found what she was looking for.

When Kirk awakes, Spock is gone from the bridge. Before the captain can find out where his first officer has gone, McCoy calls, demanding his presence in sickbay immediately. Spock's body lays on a diagnostic table, on full life support. McCoy explains that his brain is gone ... miraculously removed with some technology that the doctor has never seen before. Every nerve was sealed and there was no blood lost. However, McCoy tells him if the Vulcan's brain isn't returned to his body within 24 hours, Spock will die.

Kirk orders the starship in pursuit of the woman's ship. By following their ion trail, the Enterprise arrives at the sixth planet in the Sigma Draconis system. When Kirk and party beam down, they find a rough, frozen world inhabited by two peoples: the Morgs, who are comprised solely of men, who live on the surface in a primitive culture, and the Eymorgs, an all female group who live deep under the planet's surface. While the Eymorgs live in a highly technological society, they don't understand that technology and are trained to perform various tasks--like the operation enabling them to steal Spock's brain--by what is known as the "Great Teacher." This "teacher" was left behind by ancient technologists who once lived on the planet.

McCoy, having fashioned a device which will control Spock's body without the aid of his brain, beams down with the Vulcan to join Kirk and his party. They find Kara, the woman who beamed aboard the Enterprise. They quickly realize that Kara doesn't have the skill or knowledge to have performed the operation on Spock, and she tells them about the Great Teacher.

Finally, Kirk finds Spock's brain. The Eymorgs have hooked it up to run their central control system. The brain is now revered as the "Controller," which they hope will control their central systems for the next 10,000 years. After trying unsuccessfully to get Kara to repeat the operation on Spock in reverse, McCoy submits to the Great Teacher device and gains the knowledge needed to restore Spock's brain and save the Vulcan's life.

Without their Controller, the Eymorgs fear for their existence. Kirk suggests they share their greater knowledge with the Morgs and live together on the surface.

Is There In Truth No Beauty?

Stardate: 5630.7

In an attempt to adapt Medusan technology to Federation use, and vice versa, the Enterprise picks up Medusan ambassador Kollos, instrument specialist Laurence Marvick and telepath Dr. Miranda Jones. The Medusans have a great beauty of character, but their physical appearance causes shock to the point of insanity in humanoids.

When Dr. Jones turns down her co-worker, Lawrence Marvick's, proposal of marriage in favor of staying with Kollos, Marvick tries unsuccessfully to kill Kollos. Instead, he is driven insane by a glimpse of the Medusan. He takes over the Enterprise engines, which he helped design, and drives the ship out of the galaxy into an indeterminate region. The crew experiences acute sensory distortion and Marvick finally dies.

While the crew cannot pilot the starship back to the galaxy, it is possible that Kollos can, with Spock forming a mind meld. Kirk distracts Dr. Jones, who jealously objects to Spock contacting Kollos in this manner. Kirk discovers why Dr. Jones is able to gaze upon Kollos ... she's blind.

Using Spock's body, Kollos pilots the Enterprise back to its galaxy, but the Vulcan forgets to wear his protective visor when restoring Kollos to his box, and goes insane. Dr. Jones mind-links with Spock and draws the Vulcan's mind back to reality. She then makes a permanent mind link with Kollos and transfers with him to the Medusan vessel.

The Empath

Stardate: 5121.5

The Enterprise goes to pick up research personnel on the second planet of the star Minara. While Kirk, Spock and McCoy are on the surface, a radiation storm endangers the starship and Scotty takes the Enterprise out of orbit, sure that the planet's atmosphere will protect the landing party from radiation.

The three officers find themselves in an underground chamber shared with a mute humanoid which McCoy names "Gem." Two other humanoids, different from Gem, appear to them. They tell the men they are Vians, and take Kirk as a test subject to torture. He is assured, however, that it isn't he who is being tested. Gem, who turns out to be a fully functional empath, heals Kirk's wounds. The Vians tell the captain he must choose one of his men to be the next text subject. Each man volunteers, but McCoy wins, managing to anesthetize both Spock and Kirk, and is taken away by the Vians.

When he is returned to them, McCoy is near death. Gem attempts to cure him, but is frightened by the severity of his injuries. The Vians explain to them that they are testing Gem to see if her people are worthy as a species to be saved from their doomed sun. They are testing Gem's capacity for compassion and self-sacrifice. Overcoming her fears, Gem heals McCoy and the Vians decide that her species is to be saved. The officers are returned unharmed to the Enterprise.

The Tholian Web

Stardate: 5693.2

The Enterprise arrives in an uncharted area of space to answer a distress call from the Defiant. The starship is visible on their viewscreen, but sensors on board the Enterprise say it's not there.

Kirk, Spock, McCoy and Chekov beam aboard and spread out to investigate. Everyone aboard is dead ... apparently killed in a bizarre mutiny, although there are no life readings aboard. McCoy, in the ship's sickbay, tells Kirk that he can find no clue as to why the crew died, but has taken readings to study. Then, as his hand passes through a body and exam table, McCoy realizes the Defiant is dissolving.

Quickly Kirk orders them beamed back to the Enterprise, but Scotty explains that due to the poor stability of the space around them, he can only beam three aboard. After the usual debate, Kirk stays behind while the others beam back. When Scotty tries to bring Kirk aboard, his image wavers, and disappears. Interphase, Spock calculates, will occur in a little over two hours. In the meantime, they must wait. If the captain is still alive, they should be able to retrieve him then.

Complications arise when Chekov goes berserk and attacks Spock on the bridge. Slowly, more members of the crew fall prey to the "illness," attacking their crewmates. McCoy and his staff work round the clock to find a cure. When the doctor suggests Spock "put some distance" between the Enterprise and the Defiant, Spock explains that any movement in the weakened space could disturb both ship's positions and jeopardize Kirk's rescue.

At a little over an hour before interphase, a Tholian ship appears, telling Spock that the Enterprise has violated Tholian space. The Vulcan explains that they were answering a distress call and are waiting until they can retrieve Kirk. The Tholians agree to wait until the appointed time before taking action.

Unfortunately, when the interphase occurs, Kirk is not where he should be. Spock suspects that the Tholian's entrance into the area of space disturbed the Defiant's position. A funeral service is held for Captain Kirk, following which McCoy insists they view the Captain's last orders. Spock reluctantly agrees and the two men go to their friend's quarters and listen to Kirk's touching advice.

Uhura is the first to see Kirk's image floating before her, and for a time, McCoy thinks she's contracted the disease. But when he and Spock see Kirk on the bridge, they realize that he is, in fact, still alive.

The Tholians decide that Spock has, in fact, lied to them and opens fire. Making a decision, Spock orders the phasers fired at the ship. The Tholian ship is disabled, but soon another ship joins it and they begin 'building' a sort of web made of shining filaments. Spock analyses the web and announces that if they don't bring Kirk aboard and leave before the web is completed, they "won't see home again." At the last minute, Spock orders full power against the web and the Enterprise is thrown outside the Tholian's trap, several parsecs from their former position. The hope is that Kirk, caught in the Enterprise tractor beam when they changed position, was brought with them.

Tensely McCoy waits with a hypo of tri-ox for Kirk, whose air is running out as he's successfully beamed on board the Enterprise, alive and unharmed. In a humorous tag, McCoy and Spock convince Kirk that there had been no time to view his final orders and Kirk, somewhat disappointed that his wisdom had gone unheard, says that he hopes there isn't a similar circumstance where the two men will view the tape.

For the World Is Hollow and I Have Touched the Sky

Stardate: 5476.3

At the same time McCoy discovers that he has a year to live, the Enterprise encounters the asteroid Yonada which is determined to be artificially propelled. Its center is occupied by humanoids, whose ancestors built the asteroid "vessel" in an effort to escape the destruction of their solar system. However, the controls have become defective and Yonada is heading for collision with a Federation planet.

The people are ruled by Natira, a priestess who takes her orders from the central computer. While Kirk and Spock search for the central controls that will redirect the ship, McCoy and Natira fall in love. Kirk and Spock return to the Enterprise but McCoy, wishing to spend what little time he has left with the woman he's come to love, stays behind, marries Natira and accepts the "Instrument of Obedience" which punishes wrong thinking.

Soon after the marriage, McCoy calls Kirk, telling him that he may have found the controls for the asteroid. However, he is struck down by the "Instrument of Obedience" before he can tell them where. Kirk and Spock beam back to Yonada, remove the sensor from McCoy, and locate the controls. They manage to put Yonada back on course. In deciphering the computer's library, Spock finds a cure for McCoy's disease, and the doctor returns to the Enterprise. Natira must stay on Yonada to guide her people and so bids McCoy good-bye.

Day of the Dove

Stardate: Unknown

An Enterprise landing party beams to a human-colonized planet in answer to a distress call. A Klingon ship, apparently damaged, is detected and a group of Klingons accuse Kirk of having damaged their ship. Kang, their leader, claims the Enterprise as a prize and Kirk beams the Klingons on board, reluctantly. However, Spock is warned by Kirk and quickly takes the Klingons prisoner. Both ships seem to have received the same, false, distress call.

A malevolent entity has entered into the Enterprise computer and excites both sides to aggressive behavior. It forces the ship out of control, rushing toward the galactic rim, while isolating a number of Klingons and Enterprise crew, heightening their sense of paranoia and violence turning them against each other. Phasers become swords and the battle begins.

Spock finally realizes that the entity feeds off hatred and emotional excitation and has acted as a catalyst to provoke combat, keeping the numbers on both sides even. Kirk is able, in the end, to make a common-cause truce with the Klingons and they drive the creature out of the ship with their laughter.

Plato's Stepchildren

Stardate: 5784.2

When the Enterprise receives a distress call from the planet Platonius, Kirk, Spock and McCoy beam down to the planet's surface. There they find the planet's leader, Parmen, with a badly infected leg. The Platonians, while powerful psycho kinetics, have no resistance against physical injury. As Parmen's wife tells them, a cut or break in the skin can literally cause death. The only resident of Platonius that doesn't have "the power" is Alexander, a dwarf, who is everyone's jester and slave.

When Parmen's wound has healed and the landing party prepares to leave, they find the Enterprise's controls are frozen. Parmen has decided that it would be beneficial for them to have a resident doctor and tries to convince McCoy to remain. When he refuses, Parmen and the others try to convince him by subjecting Kirk and Spock to several humiliating scenarios. Still the doctor refuses and the three officers are locked away to ponder their plight.

After questioning Alexander, McCoy determines that the Platonians probably got their mental powers from eating the local foods. Something about Alexander's metabolism has kept him from acquiring those powers as well. McCoy prepares concentrated doses of kironide, the substance in the local food, and injects it into Kirk and Spock. Alexander, given the chance, refuses an injection. He doesn't want the same powers that his masters have.

As they discuss their next move, the shimmering of a transporter beam appear in the room and Lieutenant Uhura and Nurse Chapel appear. Without a word, they are jerked out of the room, as if controlled with invisible strings, and disappear. Kirk comments grimly that the men were apparently not entertaining enough for the Platonians.

Later, Uhura and Christine join the other officers, dressed in sparkling gowns and lavish makeup. Christine's is even vaguely Vulcan with slanted eyebrows and partially covered ears. What follows is a series of "games" designed to humiliate the Enterprise crew members and entertain the Platonians. McCoy, seated in a place of honor beside Parmen, is expected to accept the leaders offer to stay and serve as their physician.

Kirk and Spock are forced to fight each other and Spock is made to sing "Maiden Wine" to the two women. Finally, Spock is paired on a loveseat with Christine, while Kirk shares one with Uhura. They are forced to make advances on the women. The play gets nasty then, as Kirk and Spock take up whips, which they snap at their respective partners. By now, however, the doses of kironide are beginning to take effect and both officers now resist the Platonians powers and throw down their weapons.

Kirk tells Parmen that they can recreate this power whenever they want and if the Federation finds that Parmen and his people have fallen back to their old ways, there will be trouble. With this, Kirk calls for the Enterprise to beam them aboard ... along with Alexander, who will be coming with them to start a new life.

Wink of an Eye

Stardate: 5710.5

The Enterprise responds to a distress call from the planet Scalos; the call shows several Scalosians asking for assistance. Arriving at Scalos, however, the crew find only an empty city, with no life forms registering on tricorder scans. Compton, a young, inexperienced crewman samples the local water and disappears.

Beaming back up to the ship, the crew investigates while the Enterprise experiences a series of strange malfunctions. When an alien device is found in engineering, the ship is put on full alert. Back on the Bridge, Kirk sips coffee and suddenly finds himself "accelerated" far beyond the rest of his crew. After acceleration, he is able to see and interact with the missing Scalosians, who are now on his ship.

Kirk meets Deela, the Queen of the Scalosians, who specifically chose Kirk to be her consort. Deela reveals the Scalosians' plan to cryogenically freeze the crew of the ship so that they will have a ready gene pool to integrate into their radiation-contaminated one. Kirk also finds his missing crewman, Compton, and sees the effects of rapid acceleration--any damage to cells causes an accelerated death.

Kirk manages to send a message to Spock and McCoy warning them, and delays the Scalosians long enough for Spock to join Kirk in his accelerated state. Spock brings a possible antidote with him, and after stopping the Scalosians, and returning them to their planet, Kirk takes it. The Captain returns to normal, and Spock uses the advantage of his acceleration to repair several of the ship's systems, before he too returns to normal speed.

That Which Survives

Stardate: Unknown

As a landing party prepares to beam down to a previously unexplored Class-M planet, a beautiful woman, Losira, appears. She touches an ensign and kills him. Already dematerializing in the transporter beam, Kirk and the rest of his party are helpless to stop her. Losira then disappears.

The surge of power that Losira's appearance caused hurtles the Enterprise 990.7 light years away from where they were. Spock calculates that it will take 11.33 hours at warp 8.4 to return to the planet.

On the surface of the planet, Kirk, McCoy, Sulu and geologist D'Amato discover the vegetation is poisonous to humans and the rocks are made of an alloy that did not develop naturally. Losira appears again and kills D'Amato, again, by merely touching him. She vanishes, then reappears, this time for Sulu, but he avoids her and they realize she can only harm the person whose name she calls.

Kirk, Sulu and McCoy band together to keep her from killing them. Losira reappears on the Enterprise, in engineering, and kills another crewman. When Scotty insists that something "feels" wrong with the ship, they discover that Losira had sabotaged the matter/antimatter integrator. Scotty repairs the device before it has a chance to explode.

On the planet's surface, the landing party finds a chamber in the rocks that houses a computer. They realize that this is where Losira appears from. Losira appears to them again, this time in threes, so that she can touch each officer at once.

Spock and a security team arrive and destroy the computer that was projecting Losira's image. A visual recording triggered by the computer shows that the planet was once an outpost of the Kalandan race. It was ravaged by a deadly organism which supply ships unknowingly carried back to their home world. With the computer destroyed, the last of the Kalandans' civilization is also dead.

Let That Be Your Last Battlefield

Stardate: 5730.2

The Enterprise intercepts a stolen Federation shuttlecraft which contains a humanoid named Lokai. Taken aboard the ship, Lokai tells the crew he is from the planet Cheron, and asks for asylum on the Enterprise. His most distinctive feature is that he is half black and half white, starkly separated down the middle of his body.

The Enterprise tracks another vessel, pursuing at great speed. The ship's only passenger beams on board and is discovers to be another humanoid from Cheron. The difference in this man, Bele, is that his black and white skin is reversed from Lokai's. Bele claims to be Cheron's chief officer sent out to bring in political traitors, and has been pursuing Lokai. The more the two men are aboard the starship, the more Kirk realizes that the basic problem between them--and their entire race, apparently--is their opposite color. Tiring of their bigotry, Kirk decides to ignore the two guests and concentrate on his original mission; to decontaminate the planet Ariannus, plagued with a bacteria that endangers billions of lives.

When Bele takes control of the Enterprise in a desperate attempt, Kirk sets the ships auto-destruct sequence instead of allowing the hijacking to continue, and the alien returns command to the captain. However, once planet Ariannus is decontaminated, Bele takes back his control over the starship and leads it back to Cheron. What they find is a long-dead planet, annihilated by their interracial bigotry. Lokai beams down to the surface to escape Bele, who follows. The Enterprise leaves them on the surface, to decide their own fates.

Whom Gods Destroy

Stardate: 5718.3

Elba II, a planet with a poisonous atmosphere, also has a facility beneath its surface for the incurably, criminally insane. The Enterprise is bringing a new medicine with which they hope to eliminate mental illness forever.

When Kirk and Spock beam down to the facility of 15 inmates, they find that the asylum has been taken over by Garth of Izar, who was once a famous starship captain. He was driven insane by the terrible injuries he received while rescuing others. Garth convinces them that he is the head of the facility, in an attempt to gain control of the Enterprise and conquer the galaxy. He crowns himself, "Master of the Universe," and, when the officers won't be tricked into beaming him aboard the starship, he tortures Elba II's governor and then Kirk. He then sends his Orion mistress, Marta, out to the deadly surface above, only to "mercifully" spare her by blowing her to bits.

Spock, who had become separated from Kirk, returns to help the captain but finds two James Kirks. Garth learned the power of shape-shifting from a gentle race of beings that were unaware of his madness. When one of the Kirks offers to sacrifice himself to stop Garth, Spock realizes that this is the real Captain Kirk and subdues Garth. Garth is given the healing medication brought by the Enterprise crew and begins the long road to recovery.

The Mark of Gideon

Stardate: 5423.4

The planet Gideon appears to be a haven--the inhabitants are healthy and no one seems to ever die in the totally germ-free environment.

The United Federation of Planets sends the Enterprise to Gideon, in the hope that the Gideons will accede and become a member. Reluctantly, the Gideon council allows Captain Kirk alone to beam to their council chamber, and he transports off the ship. When Kirk apparently fails to arrive on the planet, the Gideon council refuses to allow more people on the surface, even for a search party.

Kirk finds himself on his own ship, where all of his crew have seemingly vanished. After searching the ship, he finds one lone, beautiful woman, Odona. Kirk determines that Odona is from Gideon, and that they are on a false ship, built on the planet's surface. When Odona becomes ill, the Gideon's plan is revealed: using Kirk's blood, Odona was infected with a disease which Kirk had recovered from--Vegan choriomeningitis. The infection is fatal, and the Gideons hoped to spread it across their world to reduce the population.

Spock beams down, discovers the false Enterprise, and returns to the real starship with Kirk and Odona, who--while cured--is still able to infect her people. Odona, the daughter of Gideon Council leader Hodan, is returned to her people delighted that she will cause a lethal plague to reduce the overpopulation.

The Lights of Zetar

Stardate: 5725.3

The Enterprise's mission is to take Lieuenant Mira Romaine to Memory Alpha, the central library for the United Federation of Planets. There she will supervise the transfer of new equipment to the facility. Mr. Scott is immediately attracted to the pretty lieutenant, and the feelings are returned.

While in orbit, an energy storm destroys all the inhabitants of Memory Alpha, wiping its computer memory banks. As a result of the storm, Romaine can predict where the storm will strike next; the Enterprise.

Despite evasive tactics by the starship, the storm enters the Enterprise where it is seen as brilliantly flashing colored lights. The lights enter Lieutenant Romaine and there is no way to remove them without killing the officer. Perusal of her file reveals a high susceptibility to empathic transmissions, making her an excellent home for the lights. The lights turn out to be non-corporeal entities from the long-dead planet, Zetar. They maintain that they have the right to inhabit Romaine's body, but Kirk doesn't agree. When Mira is placed in a pressure chamber, the Zetars, who are used to the vacuum of space, die. Lieutenant Romaine is free and presumably returns to Memory Alpha to help rebuild the great library.

The Cloud Minders

Stardate: 5818.4

The Enterprise comes to the planet Ardana to acquire zienite, a rare mineral needed to stop a planet-wide plague on Merak II. The zienite is not available, however, because the miner class Troglytes are rebelling against the rulers of Ardana, who live in the cloud-city of Stratos.

The Stratos-dwellers insist that the Troglytes are naturally inferior beings, but Kirk discovers that the Troglytes are being affected by a gas emitted during mining.

Unable to get both sides to settle their differences, Kirk traps the Troglyte leader Vanna and the High Advisor of Ardana's Ruling Council, Plasus, inside a mine. When the gas takes effect, Plasus realizes what is happening and promises to help the Troglytes. With peace restored, the Enterprise is able to secure the zienite it needs.

The Way to Eden

Stardate: 5832.3

Chasing the stolen vessel Aurora, the Enterprise rescues the thieves just before the Aurora is destroyed. The group is led by Dr. Sevrin in a search for a mythological planet named Eden, a planet reputed to be a paradise.

Since one of Sevrin's group is the son of a Federation ambassador, Sevrin is held in protective custody while his followers are permitted to be free aboard ship. But when Spock is able to deduce Eden's location, Sevrin's followers free Sevrin and take over the starship.

Reaching Eden, Sevrin takes his people down to the surface in a shuttlecraft. When Kirk leads a landing party in pursuit, they find that the planet's vegetation all secretes deadly acid, and the fruits are all poisonous. Madly refusing to believe Kirk, Sevrin bites a piece of fruit and dies immediately. With his death, his followers are taken back aboard the Enterprise.

Requiem for Methuselah

Stardate: 5843.7

Rigellian fever, an extremely deadly plague, strikes the Enterprise crew. Kirk, Spock and McCoy beam down to a supposedly uninhabited planet, Holberg 917-G, in search of the only known antidote, ryetalyn. To their surprise, they encounter Flint and his daughter, Rayna. Not pleased to have visitors, Flint orders his robot to gather and process ryetalyn, while the three officers are entertained by his daughter. Due to the robot contaminating the first batch of antidote, McCoy tells it another must be made. In the meantime, Kirk and Rayna have become attracted to each other, to Flint's jealous objection.

Spock has discovered, to his puzzlement, old masterpieces on modern supplies, i.e. a da Vinci painting done with modern oils on new canvas and an unknown Brahms waltz, written on new paper. Flint explains that he is an immortal, who wandered the Earth for centuries in various personas, including Brahms and da Vinci. He came to this planet to retire in peace and built the "Rayna" android as his companion. He had hoped that her involvement with Kirk would speed up her emotional growth, but now he has become hopelessly jealous. Not understanding such intense emotions, Rayna short-circuits and "dies."

The landing party takes the ryetalyn and returns to the Enterprise. McCoy tells them that Flint, too, will soon perish because what made him immortal was the atmosphere of Earth. Leaving it robbed him of that power.

In a surprisingly compassionate gesture, Spock uses a Vulcan mind touch to erase the painful memories of Rayna from Kirk's mind.

The Savage Curtain

Stardate: 5906.4

The Enterprise is scanned by a powerful energy source coming from the planet Excalbia. The starship had been sent to survey the planet, but it was thought to consist of nothing but a lavalike surface without inhabitants.

The image of Abraham Lincoln appears in space and requests to be beamed aboard, claiming to be the genuine Lincoln. Against McCoy's objections, Kirk and Spock beam the entity aboard. They accept his offer to visit Excalbia, where a rock-like creature named Yarnek appears. Yarnek declares that the Enterprise officers are to participate in a battle between good and evil. This is to teach the Excalbians about humanoid concepts. Fighting for the "good" are, Kirk, Spock, Lincoln and Surak, founder of the present Vulcan culture. On the "bad" side are, Genghis Khan, Colonel Green, Zora--a vicious killer--and Kahless, father of the Klingon Empire as it was now known.

When the Enterprise officers refuse to fight, Yarnek freezes the starship's engines, starting a breakdown of the matter/antimatter shielding. If Kirk doesn't win, the ship will explode in four hours. There is much plotting and counter-plotting, until only Kirk, Spock, Khan and Zora remain alive. After some philosophical discussion regarding "good" and "evil," Yarnek returns Kirk and Spock to the Enterprise and frees the ship.

All Our Yesterdays

Stardate: 5943.7

The crew of the Enterprise investigate the planet Sarpeidon whose sun is soon to go nova. Upon beaming to the surface, Kirk, Spock, and McCoy discover the inhabitants gone and a library containing the planet's accumulated knowledge.

Kirk, Spock and McCoy are surprised to find a lone inhabitant on the surface, Mr. Atoz, the librarian, who mistakes them for citizens of Sarpeidon. Mr. Atoz has been transferring people into the planet's past using a machine called the "atavachron." While investigating this unique technology, Kirk leaps to rescue a woman he hears screaming and ends transported to a period fraught with superstitions and witchcraft. Attempting to follow Kirk, Spock and McCoy enter the atavachron's portal to find themselves in a different time--Sarpeidon's ice age.

McCoy, who is close to freezing to death, and Spock are rescued by a beautiful woman, Zarabeth. While close to the portals they entered from, Kirk, Spock and McCoy can communicate with each other but little more. However, this is enough to get Kirk arrested for practicing witchcraft.

Spock increasingly finds himself attracted to Zarabeth, and disturbingly more emotional and irrational, and even goes against Vulcan custom by eating meat. McCoy convinces Spock that this time in Sarpeidon's past is linked to Vulcan's primitive past and that they must return to their own time. Zarabeth insists they cannot return to the present without dying.

In jail, Kirk is befriended by a lawyer, another traveler of Sarpeidon's present, who helps him escape to find the portal, and return to the library.

Zarabeth helps McCoy and Spock to the place where she found them. By following the sound of Kirk's voice, they find their portal and leap back into the library. Mr. Atoz leaps to his own designated past and the Enterprise, with Kirk, Spock, and McCoy safely aboard, warps from orbit just as the sun explodes.

Turnabout Intruder

Stardate: 5928.5

Dr. Janice Lester, who was once involved with Captain Kirk, harbors a deep hatred of the captain, because she, herself, has never been able to captain a starship. On their way to Beta Aurigae, the Enterprise receives a call for help from Camus II. The landing party finds only Janice Lester and Dr. Coleman, who claim that the everyone else was killed by celebium radiation. In fact, Janice is quite ill from it.

Unaware of Lester's feelings of hatred toward him, Kirk sits with her, recalling their days together. Kirk is suddenly trapped into a life-entity transfer with Janice. His personality is in her body, while she takes over his, finally becoming captain of a starship. Kirk, with Janice's essence, tries to kill her victim, but fails. McCoy transports Janice, with Kirk's essence, to sickbay to try and treat her illness. While Kirk, trapped in Janice's body, tries to convince everyone that he's really the captain, Janice takes control of the ship and diverts it to the Benecia Colony. There she plans to leave her body, that houses Kirk's essence, thereby eliminating all her problems.

The crew becomes suspicious of her actions and, when Spock tries to question her, she charges him with mutiny. They realize something is wrong and Janice/Kirk is relieved of duty. When the transfer weakens and finally breaks, Kirk returns to his body, as Janice's essence returns to hers. Janice makes a last attempt to hurt Kirk, then collapses. Dr. Coleman, in love with Janice, requests that he be allowed to care for her. The Enterprise and her crew return to their mission, with their rightful captain at the helm.
