The Fog (1976)

In the first months after the war, a period of confusion and fratricidal fighting, a Warsaw whack-job drafted into the ranks of the KBW gains the first life experiences that make him an informed citizen. Marian, a boy from Targówek, is serving in the KBW. His unit is sent to a village plagued by a band of NSZ. Marian becomes involved with a young teacher, Anka, whose brother is a member of the NSZ. During the final trial, Stefan is killed and Marian is seriously wounded and taken to the hospital. An investigation is carried out in the village. Marian does not admit that he knew about Stefan and his contacts with his sister. When he leaves the hospital, he does not find the girl, but their son, who is being cared for by Anka's parents. He takes the boy and returns to Targowek.
