High school student Scott Howard (Michael J. Fox) is seventeen years old, sick of being average and wishing he were special. His father runs a local hardware store. Scott plays basketball for his high school’s team, the Beavers, with a not-so-good win-loss record. The girl of his dreams, Pamela Wells (Lorie Griffin), is dating Mick, a jerk from an opposing high school team, the Dragons. After another of the team’s losses, Scott begins to notice strange changes to his body.
