As the Enterprise approaches planet Omega IV, they find another starship, the U.S.S. Exeter, in orbit. Kirk, Spock and McCoy beam aboard to find the ship abandoned but strewn with uniforms and crystals. The last log entry from the ship's surgeon tells them they have been infected with a deadly virus brought aboard from a returning landing party. Kirk's party beams down to the planet's surface and finds there is one Exeter survivor: Captain Ron Tracey. He has apparently ignored the Prime Directive and has taken sides in a local dispute supporting the Kohms against their arch-rivals, the Yangs. As McCoy tries to find a cure for the virus, Spock and Kirk try to make sense of the situation. They eventually realize there is an odd parallel with Earth's own history. Written by garykmcd

Stupid but Memorable
3 May 2014 | by (United States) – See all my reviews

Somehow, whenever I chance upon a rerun of the original series, this is the episode that seems to be on. It involves a gross misuse of the prime directive. A Starship Captain has gone bonkers, thinking he is on the verge of the discovery of the fountain of youth. The indigenous races seem to be able to live for centuries. The Yangs and the Kohms are the races, and they are engaged in a constant battle for superiority. Kirk gets embroiled in their business and gets knocked around quite a bit. The point is that somehow this fellow needs to be stopped and the war he is promoting needs to be stopped. The final scene where Kirk begins pontificating, is about as incredible (and I mean in a really negative way) as any scene in all of Star Trek. This may be one of the worst episodes of all time.
