Stalingrad, autumn 1942: Hitler's Sixth Army pushes into the city block by block while the Red Army refuses to give up the Volga's west bank. The film traces the battle from the first Luftwaffe bombing raids that leveled the city to the close-quarters fighting through factories and apartment blocks, where soldiers measured gains in rooms rather than miles. It follows the Soviet counteroffensive, Operation Uranus, that encircled the Sixth Army and turned a German siege into a German trap, leaving General Friedrich Paulus's men cut off without supply as winter temperatures dropped and food ran out. Archival photographs, maps, and battlefield footage track the collapse of German positions and the eventual surrender, framed as the point where the war on the Eastern Front turned decisively against Hitler. The narration lays out the scale of the losses on both sides and why historians still treat Stalingrad as the costliest single battle of the war, a siege that broke an army meant to be unbreakable.
