The Marcenat couple seem to have everything they need to be happy. However, Odile's frivolity and Philippe's jealousy drive the couple apart. Philippe, manager of the family printing business, finds solace in Isabelle, a long-time employee at the paper mill. Isabelle's routine life, entirely devoted to her work, leads Philippe to strike up a romantic relationship with the playful young Misa. But, faced with Isabelle's grief, Philippe puts an end to the romance. When Odile, inconsolable since their break-up, finally commits suicide, Philippe realizes that she was his true love.
