A coming-of-age drama in a rural French town -Marc, a 15-year old boy breaks free from his fixation with his older half-sister, Vivien and learns to trust himself and become independent. When she finally returns home after an eight year absence, young Marc is ecstatic. He is awed by her free-wheeling, independent life. He quietly follows her every move, living vicariously through her. She becomes his teacher, but as he observes her more closely he begins to see that she has no real sense of self-worth. Her promiscuity is only a mask to hide her lack of self-respect. He begins to withdraw and follow his own path. They both have unusual ideas about love: Vivien doesn't know how to say no to his fans, and Mark discovers that he likes guys.
