In 1941, France's national treasure, Leonardo da Vinci's Mona Lisa painting is moved to the Biltmore House near Asheville, North Carolina, for safekeeping.
German General Hermann Goring hears about this move and sends a special Luftwaffe detachment to America by U-boat.
Their mission is to break out a German art expert from an American POW camp and continue to Asheville to steal the Mona Lisa, leaving a masterful forgery in its place.
Unbeknownst to the Nazis, a second scoundrel has a similar plan in place. However, while his wealth may provide him with the resources to succeed, his greed may be his undoing.
Will this villainy succeed? Only a disabled Army Air Corps captain and a French art curator from the Louvre stand in their way...
