Treasure hunters Sam and Remi Fargo are exploring the Great Pocomoke Swamp in Delaware when they are shocked to discover a World War II German u-boat. Inside, they find a bottle taken from Napoleon's 'lost cellar.' Fascinated, the Fargos set out to find the rest of the collection. But another connoisseur of sorts has been looking for the bottle they've just found. He is Hadeon Bondaruk - a half- Russian, half-Persian millionaire. He claims to be a descendant of King Xerxes himself.
And he wants his treasure back.
