Kanal(1957)

Original title: Kanał

In the last few days of the Warsaw Uprising during World War II, a modest group of Resistance members remains. The band must take refuge in the sewers under the orders of leader Zadra, but it's only a matter of time before they will have to emerge. However, when they try, they are met only with intense hostility from the Nazis. Despite their attempts stay resolute through immense mental strain, it becomes increasingly apparent that they may be doomed.
