Maria joins a Pentecostal sect. A young worker, Ivan, who has fallen in love with the girl, tries to save her from the sect's influence, but he is hindered by the head of the sect, the cruel and insidious Laguta, who plays a fatal role in Maria's fate.

Upon returning from the front, Ivan Lukich discovered that his wife had been unfaithful to him. He left her and their daughter. Later, Ivan attempted to locate them, but was unsuccessful. Years passed. He now has another family, grown children, and a grandson. Quite by chance, he encounters Lisa, his daughter, who is convinced that her father died at the front.
