Based on a true story. After Poland is overrun by Axis forces in 1939, an officer and his remaining men decide to continue fighting the invaders alone, thereby becoming the first guerrillas of World War II.

During the last few days of the Warsaw Uprising following 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.

Stach is a wayward teen living in squalor on the outskirts of Nazi-occupied Warsaw. Guided by an avuncular Communist organizer, he is introduced to the underground resistance—and to the beautiful Dorota. Soon he is engaged in dangerous efforts to fight oppression and indignity, maturing as he assumes responsibility for others’ lives. A coming-of-age story of survival and shattering loss, A Generation delivers a brutal portrait of the human cost of war.
