Kirk, Spock and McCoy suddenly find themselves in an underground laboratory where they meet an attractive young woman who is not only mute but also an empath who can absorb someone else's pain. When their captors make themselves known, they refuse to explain why the three men have been taken prisoner or why they and the young woman, whom McCoy has named Gem, are there. Inexplicably, they set about torturing them for no apparent reason. Fortunately, Gem's empathic powers allow her to take away their pain, but only at great sacrifice to herself. When their captors tell Kirk that he must choose which of his men to die, their selflessness comes to the fore, leaving Dr. McCoy volunteering himself. They all soon learn that the object of the experiment is Gem herself. Written by garykmcd

As Kirk recovers from the Vian weapon on the planet's surface, he touches a nearby rock formation to steady himself. The boulder-sized rock visibly shifts under the weight of his hand. See more »


Dr. McCoy: Well, personally, I find it fascinating that with all their scientific knowledge and advances, that it was good old-fashioned human emotion that they valued the most.
Scott: Perhaps the Vulcans should hear about this.
Captain James T. Kirk: Mr. Spock, can you be prevailed upon to bring them the news?
Mr. Spock: Possibly, Captain.
Mr. Spock: [with a wry look] I shall certainly give the thought all the consideration it is due.

A Mute Empath And Lab Rats
14 January 2017 | by (United States) – See all my reviews

Season 3, episode 12. The Enterprise has arrived at Minara II to save the research group there before a supernova. Kirk, Spock and McCoy beam down and find no one there, Scotty is in command of the Ship, he moves the ship to a safe distance from the oncoming solar flare. Scotty and crew will return to the planet as soon as they feel it is safe from the solar flares. Below, Kirk and crew meet a mute empath who McCoy names Gem - she has the ability to heal. Two aliens, the Vians, appear and want specimens: Kirk, Spock and McCoy. The Vians are wanting to study them, their strength, love, courage, etc. - making the trio essentially lab rats of the Vians. They are very lucky to have Gem with them, healing them and taking away their pain. What does Gem have to do with the Vians?

Interesting episode. Gem is much like a dancer and a mime in her movements - very theatrical, beautiful. She speaks volumes without saying a word. Experiments to save Gem and her planet's people.
