The husband-and-wife treasure hunting team of Sam and Remi Fargo stumble across a WWII German U-boat in a Delaware swamp. Inside they found a curious bottle supposedly from Napolean's «lost cellar». While they look for the rest of the collection, millionaire Hadeon Bondaruk, who claims to be direct descendant of Persian emperor Xerxes the great, is also looking for that bottle. He is interested only in the label of the bottle, which holds a treasure map leading to the golden columns stolen from the Greeks by Xerxes.
