On June 6, 1944, the 2nd Panzer Waffen-SS Division Das Reich sets out from Montauban toward Normandy, a march that becomes a monthlong campaign against the French Maquis and British SOE operatives across the south of France. The film traces how a division hardened on the Eastern Front responds to ambushes and sabotage with mass reprisal, culminating in the hangings at Tulle and the destruction of the entire village of Oradour-sur-Glane, where hundreds of civilians were killed. Testimony, archival photographs, maps, and battlefield locations are used to reconstruct both the guerrilla tactics of the Resistance and the SS chain of command that ordered the reprisals. The documentary treats the campaign as a case study in occupation warfare, weighing what the delay to Das Reich's advance meant for the Normandy front against the human cost inflicted on French civilians. It closes with the postwar reckoning over who bore responsibility for Oradour, a question still argued over in France today.
