Malibu High (1979)

High-school student Kim is having a tough time: her boyfriend Kevin dumped her for rich girl Annette, her grades are slipping, she has no money, and all her mother seems to care about is cleaning. She tells her best friend Lucy that the nonsense ends today. She's been feeling sorry for herself ever since her father hanged himself. She begins working for Tony the pimp and things start to look better for her: new clothes, new car, and good grades. Kevin notices her again and Annette hates her. She then meets Lance, who frees her from turning tricks in a beat-up old van, which leads her to better clothes and nicer cars. Prostitution isn't the worst of it as she is forced to kill a man in self-defense when he tries to have his way with her being tied up. She becomes a hit woman.
