When an accident causes Dr. McCoy to go temporarily insane, he escapes to a strange planet. There, the search party discovers a device left by a superior, vanished civilization, a time portal that plays the history of Earth for them - but then Bones jumps through it into the past, causing a change in history important enough to make the Enterprise vanish. Kirk and Spock, who fortunately made a tricorder recording, must attempt to go through to just before McCoy's arrival and stop him from changing history in the US during the Great Depression, where they have no advanced technology available.

We... served together.
And you, um, don't want to talk about it? Why? Oh. Did you... did you do something wrong? Are you afraid of something? Whatever it is, let me help.
"Let me help." A hundred years or so from now, I believe, a famous novelist will write a classic using that theme. He'll recommend those three words even over "I love you."
