When the Fonz is wrongly accused and imprisoned for stealing a car he was working on, Laverne and Shirley (along with Squealy) go on a quest to capture the real criminal.
A robot called M.A.B.E.L. is sent to the camp to sabotage the military games, for which Laverne and Shirley receive the blame. But when M.A.B.E.L. gets broken, the Fonz gives her a repair and tune-up.
