War! The Klingons and the Federation are poised on the brink, and then war is declared. Kirk and Spock visit the planet Organia. Organia, inhabited by simple pastoral folk, lies on a tactical corridor likely to be important in the coming conflict. Whichever side controls the planet has a significant advantage. But the Organians are a perplexing people, apparently unconcerned by the threat of the Klingon occupation or even the deaths of others in their community. Finally, Kirk and the Klingon commander Kor learn why, and the reason will change Federation/Klingon relations for decades to come. Written by CommanderBalok

Did You Know?


John Colicos was director John Newland's first and immediate choice for the role of Kor. He got the script only two hours before flying to Los Angeles from Toronto, and read it on the plane. See more »


Sulu is left in command of the Enterprise, even though Scott is on the ship (although not on screen) and should be the acting captain while Kirk and Spock are on Organia. See more »


Captain James T. Kirk: Well, Commander, I guess that takes care of the war. Obviously, the Organians aren't going to let us fight.
Kor: A shame, Captain. It would have been glorious.

"as we are to the gnat"
7 September 2013 | by bkoganbingSee all my reviews

William Shatner and Leonard Nimoy are at a loss to explain what they're encountering on a planet called Organia. There is an imminent invasion by the Klingons that will pass this planet and its location makes it a great place for a military base.

Yet these Organians led by Peter Brocco are so docile and placid to Captain Kirk's warnings and later to the Klingon arrival led by John Colicos it defies explanation. Possibly Gandhi's non-violence taken to the extreme?

It's not of course and the explanation is something that neither human or Klingon like to contemplate. In the end the Organians become peacemakers in a most unusual manner.

One of the best Star Trek prime episodes and a favorite of mine.
