A woman, a man, a summer in Paris. The passion, the breakup, the reunion. A love story out of order. A destructive passion, a couple in real life (Michaël Cohen and Emmanuelle Béart) who become on screen a couple without limits: Jean waits for Gabrielle, his great lost love. The two lovers separated a year ago and have not seen each other again. He hopes that this night before them will be that of reconquest and romantic reunion. As soon as she arrives at his house, she tells him that she has a companion and that she is now happy. During the whole night, they will try to explain the failure of their past relationship but finally fall back into each other's arms. In the early hours of the morning, their desperate search for love resumed, as fragile as it was.
