Surrender Dorothy (1998)

Lahn is a heroin addict who will do anything for his dose. After he robs his roommate, Denis, he shows up at the door of Denis' best friend, Trevor, to see if he will hide him for a while. He, who is terrified of women, agrees to let him stay in his apartment. In return for shelter and his daily dose, Trevor turns him into his slave and then into his dream girl, Dorothy. He uses psychological tactics to twist him into doing everything he asks.
