Tommy Price (Mark Damon) is the leader of a gang of young thugs interested in thrills, hot rods, and girls. His friends bet him he can't make it with 17-year-old Rosemary Clinton (Lili Gentle). Their date turns out badly and her parents (Dabbs Greer, Ann Doran) forbid her to see him again. They keep meeting, and the relationship changes him to the extent that he plans to go to college and change his life, which delights his parents (Eddie Binns, Frances Mercer).
