In the spring of 1943, mainland Europe lay in the firm grip of Nazi Germany and the Axis Powers.  A year removed from the D-Day invasions of Normandy, Allied intelligence is formulating a plan that involves a lone serviceman - military courier, Major William Martin.  Martin would prove to be the key to deceiving the Germans of the Allied plans to liberate Sicily and alter the tide of the war.  British officials know they have only one shot to implement their plan at deceiving Adolf Hitler and are putting their faith and their resources behind a single soldier...who doesn't actually exist.
