Best friends Libby Bays and Norma Singer are victims of Emmet Bays's abuse. Norma allows Libby to lure her into her father's black Chevrolet sedan, and after dropping his daughter off at their Main Street home, he drives Norma to an abandoned salvage yard and rapes her.
Best friends suddenly become enemies. Norma, trusting no one, including her parents, to support and understand what happened to her, privately blames Libby. She seeks to avenge her role in the rape before she seeks to bring Emmet Bays to justice. To protect himself from any rape accusation, he seeds a rumor in Libby that one of Clarence Singer's Mexican workers raped Norma, and to get his daughter to help him spread it, Emmet promises Libby that he will stop molesting her.
Libby believes her father's lie. Norma wants revenge. Only that friendship that Emmet Bays destroys can save these teenagers from him.
