Beau-père
Rémi is a struggling pianist with a wife named Martine, a model who is getting too old to find desirable work, and a 14-year-old stepdaughter Marion. When Martine is killed in a car crash, Marion expresses her desire to stay with Rémi in their apartment, but is taken away by her father Charly, an alcoholic who dislikes Rémi. Marion comes back, much to her father's disapproval, and takes up babysitting to help make ends meet while Rémi gives piano lessons. Soon, Marion tells Rémi she is physically attracted to him, but he resists her advances because of her young age.
When Marion proves to be anemic, she is sent to the mountains with her father while Rémi loses his apartment and moves in with friends. A broken man, he meets with Marion and they have sex in a hotel. She comes back to live with him in a run-down and condemned house, and although he first resists any more sex, gradually gives in. While visiting, Marion's father at one point sees the two embrace. He asks them if they are having an affair, but when Rémi objects, Charly apologizes and leaves. Eventually Rémi takes interest in an older woman, Charlotte, who is also a more skilled piano player, while Marion also seeks out a substitute for him and moves back in with her father.
