Louis is a divorced father and bar manager, who feels more than affection for Sabine. They often get together during the afternoon in a hotel room. He pays for the pleasure. She also has other clients. Secretive, he confides his pain to no one, not even to his sister Agnes, with whom he is nevertheless close. A teacher, she has been married to Jean-Philippe for a long time. Love, complicity, and years spent together don't prevent moments of melancholy. One day, Agnes encounters Stephane. Now a young man, she knew him when they were children. He also hides a dark secret.
