Unhappily married couple Rut (Eva Henning) and Bertil (Birger Malmsten) take a train trip across war-torn Germany -- a landscape reminiscent of their disintegrating relationship -- in this early drama from Ingmar Bergman. Between bouts of bickering, each reminisces about past lovers: Viola (Birgit Tengroth), whose affairs with a psychologist and a lesbian dancer lead to tragedy, and Raoul (Bengt Eklund), whose liaison with Rut ends with an abortion.
