The Federation is in competition with the Klingons for an alliance with the inhabitants of Capella IV. The Capellans are a warrior tribe and there is dissension among them as to who to sign the mining rights treaty with. McCoy is familiar with their customs having once spent several months there. When a Capellan, who clearly favors the Klingons, stages a coup, Kirk, Spock and McCoy flee with the now dead leader's wife, who is about to give birth. Meanwhile, the Enterprise receives a distress call from a Federation vessel under attack and, with Scotty in command, leaves orbit. Written by garykmcd

This is the only episode in which Uhura and Sulu call Scotty by his nickname. Otherwise, they call him "Mr. Scott". See more »


About 28 minutes in (right after the rock-slide), Bones and Kirk are talking about the pregnancy. There are some sloppy audio cuts of Bones which were obviously put in after the scene was filmed, so his lips don't match up to the sound coming out. See more »


Captain James T. Kirk: First of all, I must protest the killing of one of my crewmen.
Akaar: If it was your man, was it not his privilege to die for you? I do not understand.
Maab: Their customs are different, Tier.
Kras: And different from those of my people, too, Tier. The sight of death frightens them.
McCoy: [quietly] Let me take this, Jim.
McCoy: [to Akaar] What Maab has said is true. Our customs ARE different. What the Klingon has said is unimportant and we do not hear his words.

Silly and Uninteresting
29 April 2014 | by See all my reviews

You know how you look at the TV listings and you see that Star Trek is on and you're all excited because you are in the mood. And then it turns out to be this episode. What a disappointment. The Klingons have arrived on a planet inhabited by a similar race. The guys are in danger. There is an insufferable pregnant woman who takes a shine to McCoy (I never cared all that much for Julie Newmar but I guess being on the original "Batman" helps to canonize you. Scotty does a great job of keeping things focused, making wise decisions. There is a lot of cultural byplay. In the end, I couldn't have cared less. McCoy makes a bit of a fool of himself as he talks baby talk. Don't bother.
