The Enterprise is ordered to clean up the aftermath of a doomed colony on Omicron Ceti III, a planet under constant irradiation from deadly Berthold Rays. Upon arrival, however, the colonists aren't only alive but in perfect health, with no desire to leave their new world. They are in fact under the influence of plant spores which not only keep them in good and improved health but simultaneously keep them in a placid state of happiness and contentment. Mr Spock reacquaints with Leila Kalomi, an old friend who had been (and still is) in love with him. She leads Spock into being affected by the spores, and he is thereafter, for the first time, able to express love for her in return. Eventually the entire ship's crew is affected, leaving Kirk alone to wonder how he can possibly rescue them from perpetual bliss. Written by Clive Wilson

Did You Know?


Ralph Senensky originally wanted to film the Kirk versus Spock fight scene from a wider angle, so the stunt doubles wouldn't be so obvious, but the transporter room set was too small to achieve this. See more »


At about 28:30, Kirk beams aboard the Enterprise, but there is no one left on the ship by this point to beam him aboard. Indeed, a moment later, Kirk is on the bridge of the ship -- and there confirms that no one but he is aboard. See more »


Dr. McCoy: Well, that's the second time man's been thrown out of paradise.
Captain James T. Kirk: No, no, Bones, this time we walked out on our own. Maybe we weren't meant for paradise. Maybe we were meant to fight our way through, struggle, claw our way up, scratch for every inch of the way. Maybe we can't stroll to the music of the lute. We must march to the sound of drums.

This fan favorite is most well known for its scenes of Spock falling in love, imitating a chimp and telling Kirk to get with the program or leave him alone. McCoy also has a few goofy scenes like this, and his southern drawl becomes more intense with the number of mint juleps he imbibes.

The Enterprise has been diverted to a planet which is being bombarded by lethal Berthold rays, to look for survivors in a luddite-utopian commune founded there several years ago. Remarkably, despite the killer radiation, the population is mostly intact and in great health. Just as it is becoming clear how the colony has survived, Kirk is ordered to evacuate all of them. They don't want to leave.

Ralph Senensky does a great job of directing this thoughtful D. C. Fontana episode, and the acting supersedes the standard franchise fair. Great for fans, very good for others.
