Germany at the end of World War II: Teacher Grübler lives in a small village in the Ore Mountains together with his 15-year old son Wolfgang. At school, the dutiful Grübler, a member of the NSDAP, teaches his pupils to volunteer for military service, but when his own son volunteers for the Waffen SS, he is nevertheless shocked and fears for his boy′s life. But Wolfgang starts to hate his father for his doubts: He thinks his father is a coward. In his desperation, Grübler chains and kidnaps his son to hide him in a dugout in the forest until the end of the war. In their shelter, father and son are fighting bitterly but when the Nazis who still believe in the "Endsieg" discover their hideout, Grübler sacrifices his life to save Wolfgang.

Seventeen-year-old apprentice Jonas, struggling with his ailing, proud father, pours himself into restoring a decaying ship on a Mecklenburg lake. Neglecting all else, he loses his girlfriend and support at work. After the boat burns, a reconciliatory vocational ceremony reunites him with his recovered father.

The film tells the story of the smelter brigade of a steel mill whose members are connected by a strong comradeship. Among the workers are, for instance, young Rolf, whom everybody just calls "Lachtaube" and who always comes through for his co-workers, or the likable Hubert, who works as a simple smelter again after being dismissed as the head of the steel mill. Then, there is also the stubborn Manfred, who should have become a brigadier long ago because of his experience and his competence, but this privilege is refused to him because Manfred is not a party member. Ironically, it is Manfred who hears by accident about the plans of the mill to close down the old Martin furnaces – and to lay off the smelters. When the other men learn about the plans they enter the barricades for their jobs and force the plant′s management to face the workers′ demands and criticism.
