Melvin Belli leads Kirk’s nephew’s band to take over the Enterprise.
Captain Kirk parties a little too hardy and steers the ship right into an asteroid. When he wakes up the next morning, he can’t even remember how to pronounce his own name. Spock & Doc rescue him, but not until after he gets stoned again. Oh, yeah, he also falls in love again and gets another woman pregnant, so he gets her an abortion the hard way.

Most memorable line: “Brain and brain, what is brain?” They brought back Star Trek for this?
The Enterprise goes back in time again, to the 20th century again (This saves a lot of money on sets, props, and costumes.) An alien invades Earth, disguised as an Earthling.

This was a pilot for a new show that the network liked so much they not only didn’t pick it up but they canceled Star Trek besides.
Kirk does his best to follow the Prime Directive (for a change) in order to save an old friend who gets killed anyway by the Romans (not to be confused with the Romulans).

The crew of the Enterprise discovers that, just as human beings are an unavoidable result of evolution, so is the United States of America.
