"A true story of undercover agents!"
England, 1944. Shortly before the start of D-Day, British Major Julien Howard, who leads a special group of spies, is ordered to deceive the Nazis. The Nazis must assume that the Allied invasion will take place in the Netherlands instead of France.

Their secret mission is in grave danger when one of the members of Howard's group turns out to be a spy for the Germans.
