During the Nazi occupation of a Czech city civilians are being rounded up on the slightest of pretexts and shot. One day three high school boys who crack jokes about a recently deceased "hero of the Reich" are pulled out of school by the Gestapo.

Oldrich is the runt of his village, beaten by his father, bullied by the other boys. But he has imagination on his side, and a wiry toughness they can’t defeat. The village is in turmoil, because the Nazi occupiers have just retreated and the Red Army is advancing. Oldrich dodges amid the mayhem and panic, taking his share of blows but always managing to stay one step ahead. Beautifully shot and darkly ironic, Karel Kachyna’s forgotten masterpiece jumbles reality, memory and fantasy to capture the intensity and confusion of childhood in a war zone.

In late 19th century Czech-speaking Bohemia, oppressed workers at German-owned mines and foundries revolt against their harsh working conditions. Made shortly after World War II as Czechoslovakia was falling to communism, the film resonates in Czech resentment of the German occupation.
