Mari (Marina Vlady) runs a boardinghouse for girls who are in trouble, and Juli (Lili Monori) is a young married woman who is fleeing her passionate marriage with an uncontrollable alcoholic. She has brought her young daughter along with her. Though this is not allowed under the house rules, Mari makes an exception for Juli. Both women are desperately unfulfilled - Mari has a narrow-minded and passionless man for a husband, and Juli still loves her husband, whom she recognizes as a person she cannot continue living with. The two turn to each other for comfort, and each woman gains necessary insights into her own life in seeing the other's struggles. This sober movie by feminist director Marta Meszaros was not a rousing box-office success.
