Gabe Kotter returns to Buchanan High School, where he was a member of the Sweathogs, a remedial class, and now returns to teach the newest group. After some lukewarm reception to their first effort, producer James Komack (Chico and the Man was his) and his writers were hurriedly rewriting shows. This is the pilot, with a new lead-in. Kotter (Gabe Kaplan) gets to reminiscing about his first day at school and there's a flashback to his encounter with the principal and students. He's ready to quit.
