While on a mission of mercy, the Enterprise comes across a shuttle craft stolen from Starbase 4. Its occupant is Lokai, a humanoid who is exactly half black and half white. Soon his pursuer, Commissioner Bele, arrives on board demanding that Lokai be turned over to him for transport to their home planet where Lokai has been convicted as a terrorist. Both men have extraordinary powers and it turns out that the pursuit has lasted 50,000 years. Their hatred of one another is racially based and, despite attempts by Kirk and others, they are not prepared to reconcile. The pursuit ends on their home planet where they learn the fate of their races. Written by garykmcd

Did You Know?


The SciFi Channel, the DVD, and the remastered version added some new scenes that were not in the original and VHS version. After Kirk makes his first log entry at the beginning of this episode, he asks Chekov about estimated time to Ariannus, tells Uhura to contact them to tell them that decontamination is to begin on arrival, and asks Scotty if it will it present any danger. Then after the shuttle is bought to the hangar deck, there is a shot of the shuttlecraft docking with the Enterprise. Sulu then calls Kirk in the turbolift to inform him that hangar doors are closed. Finally, there is a shot of Kirk and Spock in the hallway before they meet with the guards. See more »


Bele comes charging out of the turbo-lift while chasing Lokai, and knocks a passing crewman to the floor. The crewman clearly braces himself to take the impact, rather than flinching away, revealing that he knows what's coming. See more »


[the Enterprise is within scanning range of Cheron]
Captain James T. Kirk: What are you picking up?
Mr. Spock: Several very large cities, uninhabited. Extensive traffic systems, barren of traffic. Lower animals and vegetation encroaching on the cities. No sapient lifeforms registering at all, Captain. There is no evidence of natural disaster. yet there are vast numbers of unburied corpses in all cities.
Captain James T. Kirk: You mean, all the people are dead?
Mr. Spock: All dead, Captain. They have annihilated each other. Totally.

One of the Best Star Trek Episodes is not as "Black and White" as It Appears
4 February 2017 | by classicalsteveSee all my reviews

This episode has been criticized because it seems its main point is applied with a sledge hammer. And yet, if you watch the episode carefully, there are subtle hints that there's a lot of blur about what its ultimate message could be. The Starship Enterprise has inadvertently crossed paths with two alien beings who have been at odds for 50,000 years, Lokai and Bele. A shuttlecraft was stolen from a Starbase 4 and the Enterprise is in pursuit. They use a tractor beam to "rescue" the shuttlecraft and a strange humanoid who is black on one side and white on the other. His name is Lokai and he said he "borrowed" the shuttlecraft to escape a commissioner from the planet Cheron who has been pursuing him. When McCoy examines him, he determines that Lokai would be regarded as a superhuman when compared to average humans from Earth.

Shortly thereafter another humanoid obviously from the same planet appears on the Enterprise, Bele. He says the Enterprise holds "precious cargo": Lokai. Bele also has the same trait of having a black side and white side. We learn that Bele regards Lokai as of an inferior race and that Lokai's "people" were destroying their civilization. By contrast, Lokai contends that Bele's people enslaved his people. Bele also demonstrates abilities far above those of earth humans. When the difference between the two is finely revealed, Kirk and Spock are somewhat flabbergasted as to the characteristic which distinguishes the individuals.

While this story device of humanoids with a black side and a white side may appear to be an obvious commentary on contemporary racial relations, the story does well to keep from portraying one side as being "right" and the other "wrong". Lokai's claims his people were oppressed by the people represented by Bele may at first seem like the obvious choice for our sympathies. But then we learn that Lokai's people engaged in destruction on a mass scale. He also continually admonishes the crew for not carrying out justice because they are not willing to kill Bele. Simultaneously Bele believes he is pursuing not only Lokai but justice and that his apprehension of Lokai represents the greater symbolic rightness of "justice".

This is a subtle story if you examine its depth. Its not really about who was right or wrong in terms of the "facts" of who was more or less oppressed and/or who was more destructive. The final message is that no matter which point of view may be right, the real villain is the hate which emerges from the conflict. And as the final scenes attest, hate becomes the overriding destructive force which may be the unintended consequence of pursuing justice, however that is defined.
