The Sweathogs host a radio station at school, but Horshack's ratings are so bad that he gets canceled. In his final broadcast, he becomes a radical radio broadcaster causing his ratings to soar.

Woodman brings a computer into the Sweathogs' class to teach their lessons and the class grades increase dramatically. But now, Kotter is jealous because the computer is making him feel obsolete.

The new girl in Kotter's class declares that she is going to become a Sweathog, but the other Sweathogs strongly oppose her joining their group. So she pulls a stunt to prove her worth which backfires getting the Sweathogs nearly expelled.
