In the spring of 1913, Jean Servin, a son of a family, became friends with Roberte, a little midinette. He leaves her a few months later to marry Cécile Breton. The years go by. Jean becomes an important businessman. One evening, he meets Roberte, who has become the wife of a wealthy American. She does not love her husband any more than he loves his wife. They recall their memories. They seem to still love each other. They plan to rebuild their lives. Together, they will spend a few days in Dieppe, as they did in the past after their first meeting. They feel so different from what they were twenty years ago that they understand that the past cannot live again.
