 December, 1944. The Nazis, in the face of the onrushing Allies, turned and pushed into the Ardennes Forest in Belgium and Luxembourg for what would be their last major offensive of World War II. During the Battle of the Bulge, as it is now called, they surrounded the town of Bastogne, Belgium, trapping the US Army 101st Airborne Division in the town. To make matters worse for the 101st, thick clouds covered the area for most of the battle. This prevented the Allies from providing air cover and air-dropped supplies to their troops on the ground. This film focuses on one squad of the 101st as they wait for the clouds to break.. Meanwhile, they must survive German spies in US Army uniforms, German artillery, winter weather, dwindling supplies, and the fear of being trapped by a hostile force.
