Synopsis: During World War II, a hand-picked group of American GI's undertook a bizarre mission: create a traveling road show of deception on the battlefields of Europe, with the Nazi German Army as their audience. The U.S. 23rd Headquarters Special Troops used inflatable rubber tanks, sound trucks, and dazzling performance art to bluff the enemy again and again, often right along the front lines. This little-known unit's knack for trickery was crucial to Allied success in World War II, but their top-secret mission was kept quiet for nearly 50 years after the war's end.
