Stardate: 4842.6 --The Enterprise is sent to deflect the path of an asteroid that is on a collision course with an M-Class planet. They reach there with enough time to go down to the planet's surface and explore it. Kirk, Spock, and McCoy beam down and find the planet is much like Earth. It is even populated by groups of people similar to Native Americans. Kirk goes missing and the Enterprise is forced to leave him behind and divert the asteroid's path without him.

Goof--Given the urgency of heading off the asteroid, what was Kirk & co. doing on the planet surface at the start of the story? This seems an unnecessary waste of precious time - their ability to confirm the presence of human life from orbit, via ship's sensors, had long since been established.
Trivia--Paradise Syndrome - though not officially recognized as a mental condition by psychologists - is a term conferred upon those who feel dissatisfied despite having achieved all their dreams. (Here it is used merely to describe someone who is overworked and needing a break - whether ostensibly Captain Kirk or obliquely series creator Gene Roddenberry.)
Space: the final frontier. These are the voyages of the starship Enterprise. Its five-year mission: to explore strange new worlds, to seek out new life and new civilizations, to boldly go where no man has gone before.
