 Stock car racer Tommy Callahan (Fabian) is forced to join Pete Madsen s (Jan Murray) thrill circus after his blackouts cause a fatal accident that gets him thrown off the circuit. He shows Pete s daughter Francie (Annette Funicello) and her boyfriend Eddie Sands (Warren Berlinger) everything he knows about driving. Eddie takes up with Tommy s girl Annie Blaine (Diane McBain) after winning the first time out. They become fierce rivals by the next race, during which Tommy remembers driving over his brother with a go-kart and Eddie hits the wall.
