To Turn a Trick (1967)

Working late one night at her job as a photographer's assistant, Inger is raped by a client while two nude models force her to submit. Overwhelmed by shame, she runs away and attends a party where drugs stimulate unrestricted sexual activity. Emotionally unstable, Inger turns to lesbianism. She is drawn deeper into a life of depravity, until she is killed by an overdose of drugs.
