Screen adaptation of Julius Fucik's story about communist fighters.

Set in a bleak, filth-ridden provincial hospital, a disillusioned doctor begins to find the philosophical ramblings of a mental patient more stimulating than the company of "sane" society. As their relationship deepens amidst the grimy and decaying wards, the doctor's own mental health is called into question by his suspicious colleagues.

A small town is one day visited by a priest who is there on a secret mission. He is a member of the Inquisition sent to investigate the activities of a local miller. The miller and his son are the descendants of an old family whose ancestral home burned down a century ago, but was rebuilt from scratch. The miller inherited much of his knowledge about the land, water, and a building's stability from generations of family experience. His reputation for finding water and predicting when a structure might collapse have come to the attention of the Inquisition -surely he must be in league with the Devil.

Telling the prisoners of a death camp. Boxer Tony Majer, who got into a concentration camp for a fight with the Gestapo, remembers the murderous work in quarries, on the cruel torture of the Nazis and prison solidarity that helped him survive.

The family is connected with Prague's "Kolbenka", the ČKD locomotive factory. Grandfather Antonín, already retired, son Rudolf, a master in the locomotive assembly section and grandson Antonín, a promising football player.

The film is linked by retrospective sequences from the lives of Antonín the Elder and Rudolf, especially from the war years. It is a realistic take on working-class life, unencumbered by ideology (despite the opening dedication), featuring well-known and time-tested actors in mainly male roles.
