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 stepfamily, Marion. When Martine is killed in a Traffic collision, 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.
