Plot Rémi is a struggling pianist with a wife, 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 Simone and Nicolas. 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. During a surprise visit, Charly at one point sees the two embrace. He asks them if they are having an affair, but when Rémi objects, Charly apologizes and leaves. While babysitting a little girl, Nathalie, Marion finds she has developed the flu and rushes to Rémi for help. Rémi borrows money for the medicine, and while seeing the physician, meets Nathalie's mother, Charlotte. Rémi takes interest in Charlotte, who is also a skilled piano player, and begins pursuing her.
