In this light-weight adolescent adventure, busty Tommy Boyd (Betsy Russell), a tough-gal mechanic who runs a garage in East L.A., would rather spend time riding her motorcycle and playing B-ball with the street kids than fussing with fashions and other feminine cliches. She does find time to make love with her handsome boyfriend Randy Starr (model Jerry Dinome), a racecar driver who is prettier than she is. Unfortunately for her, he gets tired of her masculine ways, and they begin to fight. Eventually, they decide to solve their differences on the racetrack of the Daytona 500.
