 This is the story of the senior-level preparations for the D-Day invasion on June 6, 1944 from the time of Dwight D. Eisenhower s appointment as the Supreme Allied Commander in Europe, to the establishment of the beachhead in Normandy. The film recounts many of the trials and tribulation Ike had to face, not the least of which were the many prima donnas surrounding him (Patton, Montgomery and especially de Gaulle) and the need for tact and diplomacy to bring all sides together for what would be the largest amphibious assault ever attempted.
