When the bewitching Florence (Jeanne Moreau) and her lover, Julien (Maurice Ronet), plot to kill Florence's unsuspecting husband (Jean Wall), they don't count on a technical glitch -- a broken elevator -- getting in the way of the perfect murder. Louis Malle directs this haunting French thriller in his feature film debut, an impressive achievement heightened by the film's memorable improvisational score composed by jazz legend Miles Davis.
