At the end of World War Two, Polish people move to the western lands vacated by Germans. But some ruthless profiteers pose as government representatives and intend to make off with loot from a deserted town they took over. One honest man stands up against them because he believes these goods belong to the people.

Warsaw after the fall of the Warsaw Uprising. The Germans expel the civilian population and then proceed to systematically destroy the city. The capital is transformed into a sea of rubble, among which a few survivors hide – modern-day Robinsons. One of them is Piotr Rafalski, who rescues Krystyna, a wounded Jewish woman. Three soldiers of the People's Army, cooperating with a Soviet telegraph operator, are also in the city.
