List of Star Trek: The Original Series episodes

"The Conscience of the King" is an episode of Star Trek: The Original Series. It is episode #13, production #13, and aired on December 8, 1966. It was written by Barry Trivers and directed by Gerd Oswald.

The episode takes its title from the concluding lines of Act II of Hamlet: "The play's the thing/Wherein I'll catch the conscience of the king."[1]

Overview: Captain Kirk crosses paths with an actor suspected of having been a murderous dictator many years before.


On stardate 2817.6, the Starship USS Enterprise has been called to Planet Q by Dr. Thomas Leighton, a research scientist and friend of Captain Kirk. Dr. Leighton had claimed to have discovered a new synthetic food source. As a result, the Enterprise diverted from its scheduled course to come to the planet.

Upon arriving, however, Kirk discovers that the synthetic food discovery claim was just a ruse employed by Dr. Leighton to bring Kirk to Planet Q. Leighton reveals to Kirk his true motivation is for Kirk to confirm Leighton's suspicions that Anton Karidian (Arnold Moss), the leader of a Shakespearean acting troupe currently on the planet, is, in fact, Kodos "the Executioner", the former governor of the earth colony of Tarsus IV, who was responsible for the massacre of over 4000 people — including members of both Kirk's and Leighton's families — 20 years before.

At first, Kirk is unwilling to believe Dr. Leighton's accusations. He states he is satisfied with the official version of history that Kodos died in the aftermath of a battle between his loyalists and relief forces from Earth and that a burnt body discovered in the wreckage was that of Kodos. He begins to doubt those convictions when Dr. Leighton is found dead the next day under mysterious circumstances.

Kirk contacts another friend of his, the captain of the transport ship that is to pick up the acting troupe, and convinces him to miss the pick up, effectively stranding the troupe. He then finagles Karidian's daughter, Lenore, into bargaining for transport on the Enterprise in return for a special performance for the crew.

Kirk's actions arouse Spock's suspicions as it is against regulations for Starships to transport civilian passengers and as the troupe's destination, Benecia colony, is many light years off their scheduled course. After doing some investigation on the ship's computer, he discovers that former Governor Kodos had ordered the executions of more than half Tarsus IV's population after the food supply was all but destroyed by a fungus. He also uncovers evidence that Kodos applied his own personal theories of eugenics when he chose who lived or died. Furthermore, the vital resupply ships that could have saved the whole colony arrived much sooner than Kodos had anticipated rendering all the executions unnecessary.

The computer research also reveals that there are no records of Karidian's existence prior to Kodos' death; that there were nine known people left after the massacres who could identify Kodos, were he still alive; that, in the intervening years, seven of these had died, all under mysterious circumstances; that in each case of the deaths of the former witnesses, Karidian's acting troupe has been somewhere nearby; and that the final two surviving witnesses — Captain Kirk and Lt. Kevin Riley — are both on board the Enterprise.

Spock and Dr. McCoy confront Captain Kirk with Spock's evidence and his concern that assassination attempts will be made on Lt. Riley and Captain Kirk. Kirk confesses that he is unsure if Karidian is Kodos and he is unwilling to make such an accusation without proof. A further complicating factor is that Kirk has started falling in love with Lenore. However, after Riley is poisoned and left in a coma, and the ship is almost damaged by a phaser on overload left in Kirk's quarters, Kirk decides to confront Karidian by having him read the sentence Kodos pronounced before each execution so that he can compare Karidian's voice print with that of Kodos stored in the computer. Even after he obtains a near match, however, he is still unwilling to make such a damning accusation.

Meanwhile, Lt. Riley, recovering in sickbay, overhears Dr. McCoy's log entry and learns that Karidian is suspected of being Kodos — the man responsible for killing Riley's family. Riley sneaks out of the sickbay and steals a phaser gun, clearly bent on revenge. He heads for the ship's theater where the Karidian troupe has begun their performance of Hamlet.

Lt. Riley sneaks backstage, phaser in hand, to exact his revenge on Karidian. Kirk discovers him before he can act and persuades him to surrender the weapon. Their conversation is overheard by Karidian and Lenore who go backstage to investigate. Karidian, who for twenty years has tried to forget his past and shield Lenore from it, learns to his horror that his adoring daughter has (by her own admission) been on a crazed crusade to protect him by assassinating the witnesses. She plans to complete her killing spree at the conclusion of the performance by eliminating the last two witnesses — Kirk and Riley.

Lenore then snatches a phaser from a nearby security guard and takes aim at Kirk. Desperate to prevent any more bloodshed in his name, Karidian/Kodos jumps into the line of fire as Lenore tries to shoot Kirk. Kodos takes the shot, dying. Lenore breaks down and goes to a mental hospital; she hallucinating nothing unpleasant had happened.

40th Anniversary remastering

This episode was remastered in 2006 and aired September 22, 2007 as part of the remastered Original Series. It was preceded a week earlier by the remastered version of "The Galileo Seven" and followed a week later by the remastered version of "The Man Trap". Aside from remastered video and audio, and the all-CGI animation of the USS Enterprise that is standard among the revisions, specific changes to this episode include:

  • The planets the Enterprise orbits have been given more realistic appearances.
  • During a scene where Kirk talks to Lenore, the stars outside the room's viewport have been given animation to show the Enterprise is at warp.


Zack Handlen of The A.V. Club gave the episode an 'A-' rating, noting strong performances from the actors including a "great Spock/McCoy dynamic" and "some very credible acting from Shatner".[2]
