Despite Rico's assurances that it is all part of the act, Joanie is upset over the mingling that occurs between Chachi and several young women after he performs at Al and Louisa's newly opened restaurant in Chicago.

Joanie notices a guy looking at Annette during a performance at Delvecchio's, and she and Chachi introduce Annette and the guy, Wendell. They quickly hit it off and decide to get married within three weeks of their first meeting. Prior to the wedding rehearsal, however, Wendell makes a pass at Joanie.

With nothing to do during the day, on the advice of Chachi, Joanie starts hanging out with her roommate who attends college. On behalf of the band, she accepts an offer from the fraternity to play at one of their parties. Chachi thinks it would be beneath them to perform at such an event and becomes resentful of Joanie's new life.

Meanwhile, Al tries to get in shape.
