Francois Truffaut's classic tale of a love triangle which takes place over 20 years, both before and after World War I. Jeanne Moreau stars as Catherine, the beautiful and unpredictable woman who maintains a delicate relationship with two friends, the quiet German Jules (Oskar Werner) and the romantic Parisian Jim (Henri Serre). The War intervenes and drives the men to the opposing fronts; afterwards, the two quickly resume their friendship, but the balance of their relationship with Catherine is now upset by more adult concerns.
