Gabriel Kotter is a teacher in Brooklyn, New York who ends up teaching at his old alma mater: Buchanan High School. He has been assigned to teach the remedial students, better known as the Sweathogs, a group to which he used to belong.

Tired of her reputation as easy, Rosalie Totsie tells the Sweathogs that she's pregnant -- and that one of them is the father -- in an effort to make the boys admit that the tales they tell about their "fun dates" with her aren't true.

Vinnie runs for student body president, but his campaign is a disaster, despite Gabe's efforts.
