By the later years of the Second World War, Allied forces are advancing on three fronts at once, squeezing the Axis powers from east, west, and south. This episode follows that final push through Europe, tracking the military campaigns that bring soldiers face to face with something they had not been prepared for: Hitler's camps. As Allied troops move through liberated territory, what they find becomes the first concrete evidence the outside world has of the Holocaust, and the film uses archival footage and expert narration to walk through how that discovery unfolded on the ground. The focus stays on the intersection of strategy and consequence, showing how the mechanics of closing in on Germany also meant closing in on the truth of the camps. It is a straightforward, footage-driven account of a turning point where military victory and historical reckoning arrive at the same moment.
