The last eleven months of the Second World War in Europe unfold through archival footage and historian commentary, tracking the collapse of Nazi Germany from two directions at once. D-Day and the push through France open the film, followed by the Red Army's massive offensive grinding in from the east, the two Allied forces closing on Berlin from opposite sides while their governments already eye each other with suspicion. Footage of the concentration camps as Allied and Soviet troops reach them marks the film's grimmest turn, presented without softening. The final stretch narrows to Hitler's bunker in Berlin, reconstructing the last days through surviving accounts and footage as the city falls around it. Historians appear throughout to place the front-line movements in strategic context and explain the geopolitical tension building between the Western Allies and the Soviets even before the war ends. The film treats the endgame as both a military collapse and the opening move of the postwar standoff that followed.
