Set in the 17th century. A convent in a small town is being visited by high-ranking Catholic official trying to exorcise the nun supposedly possessed by demons. A local priest have been burnt for creating this condition by sexual temptation of the nuns, especially the Mother superior who bring on the collective hysteria of the group. There is another young priest who is to help with the exorcism. His first meeting with the convent head, Mother Joan of the Angels, has her seemingly possessed by Satan - she yells blasphemies and incites the priest. She begs the priest to save her and to help her to be a saint.

Rumsza, the elderly railwayman, leading a sedate life with his wife, misses his only remaining son (two older boys were killed in the war). Joziuk finally returns from the military in the first scene but with the pregnant Zosia, while Rumsza expected him to marry Celinka, the daughter of Krywka, his only friend and neighbour. The hero will not accept the new situation; he throws his son and Zosia out of his house. Celinka is distressed but she still harbours hope for Joziuk. The birth of the child changes the situation: Rumsza accepts his son's relationship but Celinka decides to leave.
