The Enterpise is approached by an ion-propelled craft (much to Eng. Scott's liking); from it enters a female who renders everyone unconscious. When the crew wakes up, McCoy finds Spock alive in sick bay but with his brain surgically removed. McCoy urges its quick restoration if he's to survive at all. Desperately Kirk follows an ion-trail to a system where he gambles on an icy planet populated by a simple-minded all-male race of large cavemen who attack them. The landing party captures one, who says Kirk and crew are small like 'The Others' - bringers of pain and delight - whom they fear. McCoy brings down Spock's body, mobilized with a mechanical brain-substitute installed. They enter the acclimatized, underground dwelling of 'The Others' - a similarly simple-minded all-female race of enslavers - and overpower female Luma by surprise. Kirk makes communicator contact with Spock, who knows not where he is but is aware of autonomic functions. As they finally find Kara, the female ... Written by KGF Vissers

Did You Know?


Written by Lee Cronin, the pseudonym of Gene L. Coon. Some have assumed that it was used because he was unhappy with the results. Actually, it was 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 »


The planet in question has repeatedly been labeled as "Sigma Draconis 6," but when in the lair of the Eymorg, Kirk's log entry refers to it as "Sigma Draconis 7." Sulu's subsequent log entry also refers to the planet as "7." See more »

Best Episode Ever!
26 March 2011 | by (United States) – See all my reviews

This one's got it all! Red Alert right off the bat! Then a hot chick dressed like a B-52 beams on board and everything goes nuts! On the planet we get a clue into the classically old school sci-fi idea of Cave people and space people. The cave men are stupid and they all have exactly the same hair and beards. Then we find out there's a whole city of hot chicks who live underground.

There are a lot of classic puzzled looks from the actors in this episode. And it's brilliantly contrasted with shots of the stone faced brainless Spock. And finally we get to see McCoy wig out with some awesome under the chin camera work.

The new 3D Enterprise looks killer. They took the classic Enterprise and were able to get some great camera movements with cgi. And the details on the ship are wicked. First class job all the way.

And for me, almost nothing is funnier than the mechanical Spock seizing the pain giving device from the space chick.
