Jean is living an unsophisticated and stable life with his lovely wife and son. One day, when he went to school to pick up his son, Jean meets his son’s homeroom teacher, ‘Mademoiselle Chambon’, and promises to be a teacher. As he falls into the delicate and elegant attractiveness of Chambon, the ordinary life of Jean is stirred. It is a calm and touching love story, typical of a French film. The attraction between a plasterer, a blue color laborer working in rough construction, and an intelligent lady who teaches and plays violin is expressed modestly. Veteran French actor Vincent Lindon as the main character who is agonized between love and family; Sandrine Kiberlain plays Chambon who is attracted to an unfamiliar man.
