After a prolonged period of separation, world famous pianist Charlotte (Ingrid Bergman) decides to visit her daughter, Eva (Liv Ullman). Once there, she is surprised to find that her other daughter, Helena, is no longer staying at the mental institution where Charlotte placed her, but is now living with Eva. As day moves into night, mother and daughter open up about their feelings and misgivings toward one another. Before long, Charlotte, who chose her musical career over fulfilling her role as a mother, is forced to reappraise her life and the choices she has made. By the time the night is over, the relationship between these two women undergoes a profound change. Winner of a host of international awards, this stunning and beautifully observed film features an historic union of two of Sweden's greatest international talents, Ingrid Bergman and Ingmar Bergman, working together for the first and only time.
