Angel Trilha sonora (1983)

Molly, 15, is the star student of her high-school class, and nobody suspects that she earns money at night as prostitute "Angel" on Sunset Boulevard. The well-organized separation of her two lives is shattered when two of her friends are slain by a necrophile serial killer. She's the only eyewitness and becomes a target herself. Investigator Detective Andrews helps her to not only survive but also to query why she keeps humiliating herself and get her to stop.
