Fifteen-year-old Connie Wyatt (Dern) may be too young to drive, but she's already driving the boys crazy. Her suspicious mother (Mary Kay Place) wants to keep her safely at home, but free-spirited Connie would rather while away the languid summer days hanging out with her friends and flirting with boys at the local burger stand. But when she flirts with an older, handsome and predatory stranger (Treat Williams), she isn't prepared for the frightening and traumatic consequences.
