In December 1944, Germany launched a secret counter-offensive through the Ardennes forest, catching Allied commanders off guard and driving a wedge into their lines that gave the battle its name. This film traces the planning behind the attack, from Hitler's bunker complex at the Eagle's Nest to the fortifications of the Siegfried Line, and asks how a regime already losing the war assembled the men and machines for one more major push west. It looks closely at the King Tiger tank, the heaviest armor Germany fielded, and at the weather that grounded Allied air support long enough for German columns to advance. The narration weighs the role of deception operations and the so-called Wonder Weapons Hitler hoped might still change the war's outcome, against the fuel shortages and manpower gaps that doomed the offensive from the start. Archival footage and maps track the fighting through the Ardennes as the German advance stalls and the Allies regain the initiative.
