Landing party meets some REALLY old young people.
Kirk, Spock, McCoy, Scotty, and someone else become infected with a disease that causes massively increased aging, Chekov does not. The struggle is to find a cure before they die of old age. The subplot is Kirk’s failing command abilities, leading to a hearing on his competence.
Highlights:
Two infected people in the intro
Chekov’s quips
Kirk’s quick nap
Spock’s loyalty
McCoy’s quick nap
Spock’s truly dramatic performance/reactions
good old corbomite
Lowlights:
tepid Kirk/lady-of-the-week romance
some old overacting
overly dramatic hearing
Kirk’s really bad old performance/reactions
McCoy’s lip-licking
