Late September 1941, the Wehrmacht turns toward Moscow. Operation Barbarossa has already gutted the Soviet Union, and Hitler bets everything on Operation Typhoon, a final push to take the capital before winter closes in. Built from diary entries left by German frontline doctors, disillusioned officers, and civilians starving inside Leningrad and Moscow, the film tracks how the campaign came apart: mud that swallowed trucks and tanks, supply lines stretched past breaking, and men freezing in summer uniforms while temperatures fell far below anything the army had planned for. Zhukov's winter counter-offensive arrives as the hinge point, turning an army that had seemed unstoppable into one fighting for survival within weeks. From History Hit, the film relies on first-person testimony rather than a single narrator's overview, letting soldiers and civilians describe the collapse of German momentum and the human cost on both sides as the Eastern Front settled into the war of attrition that would eventually break the Wehrmacht.
