Véronique Chambon (Sandrine Kiberlain), a single schoolteacher and Jean (Vincent Lindon), discover an unexpected bond that causes them to question the direction of their lives. They move in different social circles but their relationship develops and their lives begin gradually to unravel.
In a time of war and disease, a young officer gallantly tries to help a young woman find her husband.
Pattern never changes. She finds lonely, anonymous, almost invisible women doing menial jobs, becomes their friend and confidante and then kills them and takes their identity, their job and their apartment. Police investigator Judith Corel serves as bait in an attempt to trap the chameleon killer.
