June 6, 1944, 6.30 a.m.: A huge armada of western Allied troops reaches Normandy. Around 30,000 soldiers are to throw them back into the sea and secure Hitler's rule in France. The documentary depicts the exact course of the fateful »longest day« that initiated the liberation of Western Europe from Nazi rule. The special feature: The original black-and-white film footage was hand-coloured shot by shot using a special process. This gives the iconic images a never-before-seen feature film quality.
