When Hamilton High’s Prom Queen of 1957, Mary Lou Maloney is killed by her jilted boyfriend, she comes back for revenge thirty years later.

Brad, Steve, Hue, and Marvin are four get-nowhere boys who are forced into summer school, ending up at Cockswell Academy under the supervision of Principal Arsenault. The boys play a game where they earn points for every girl with which they score. On misadventures of their own, they decide to go for the ultimate 100-point score, Mona Lott, the new French teacher. But when they're unable to get a shot at her, they end up in the unforgiving clutches of the principal. After all is lost, they take one final chance during the school's anniversary celebration.
