Jeanna (Esther Garrel) is a 20-year-old young girl. After just ending a failed relationship, she decided to return to her long-lost father Gilles (Eric Caravaca) to rekindle the estranged father-daughter relationship. Gilles and his wife broke up for many years and have been tossing around between different women. What Jeanna didn't expect was that when she returned home, she actually met a girl Ariana (Louise Chevillotte), who was almost as old as herself. This girl is her father's current lover. At first, Ariana's presence made Jeanna feel very uncomfortable, because although this girl is young, she has a very rich emotional experience and is currently dating many men. But over time, a wonderful relationship gradually developed between Jeanna, Gilles and Ariana.
