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 screenplay was based on a story by Lee Cronin, the pseudonym of Gene L. Coon. He used a pseudonym because he had left Paramount and was under contract with Universal, so he was not supposed to be working for Paramount as well. See more »


When Kirk agrees to let Bele see Lokai in Sick Bay, he calls for Mr. Spock to go with them and Spock is seen entering the turbo lift behind the captain. But when they arrive in Sick Bay, Spock is not with them nor is he seen during that lengthy scene, but when Kirk returns to the Bridge, Spock is again with him when the turbo doors open onto the bridge.

[Bele and Lokai are bi-colored aliens whose skin is white on one side and black on the other, except on differing sides]
Bele: You're finished, Lokai! We've got your kind penned in on Cheron into little districts, and it's no good to change. You've combed the galaxy and come up with nothing but mono-colored trash, do-gooders and bleeding hearts. You're dead, you half-white!
Lokai: [to the crew] You useless pieces of bland flesh.

Painful Episode
13 October 2013 | by (United States) – See all my reviews

When I was little, Star Trek would come on once a week in syndication. There were no VCRs, ITunes, DVDs, etc.

One Saturday afternoon, this was the episode. It was horrible. No good guy, no bad guy, no ship V. ship space battles, etc.

The next week, the station messed up, and instead of another episode, showed this one again.

The horror of this rotten episode twice in a row, and having to wait another week.

I would rather watch Spock's Brain than this episode. But, it is not like all TOS episodes are great. Some are pretty bad, but the concept was so great you just had to watch them all.
