Mistress

Olivier, a young and uncouth provincial, teams up with his friend Mario to sell art books door to door in Paris. When they try to sell books to Ariane, an attractive woman in her dressing gown, she invites them into her luxury apartment and asks them to fix her overflowing bathtub. After catching the intruders, she asks Olivier to urinate on a client's face. He becomes Ariane's live-in lover, participating in her dominatrix activities with her clients. As Olivier becomes more familiar with her work, he also discovers that Ariane has a son, leading him to attempt to "fix" her and give her a better life.
