François Truffaut co-writes and directs this classic French drama centred on a love triangle which takes place over 20 years, both before and after the First World War. Jeanne Moreau stars as Catherine, the beautiful and unpredictable woman who maintains a delicate relationship with two friends: the quiet Austrian writer Jules (Oskar Werner) and the romantic Parisian Jim (Henri Serre). The outbreak of war intervenes and drives the two men to serve on opposing sides of the conflict. When they return Jules and Jim attempt to rekindle their friendship, but they soon discover the balance of their relationship with Catherine has been irrevocably altered.
