Dzien oczyszczenia (1970)

The film is set in the summer of 1944. The Home Army branch operating in the Sadecki region is decimated by the Germans during an attempt to retrieve a drop of weapons and ammunition from England. About 20 soldiers break out of the encirclement, including the commander, Major "Dziadek", and his deputy, Captain Stanczyk. Partisans are trying to get to the ruins of a nearby castle where the last ammunition container was supposed to fall. The commander sends two men to reconnoiter the castle, but only one returns, and without any ammo.
