Prohibition has come to an end and bootlegger Frank "The King" Argos has also come to the end of his life. He asks Eliot Ness to become the executor of his estate but Ness declines, for obvious reasons. He's left everything to his son Charlie, who was declared missing in action at the very end of World War I. When his minions find that life The King's money is not very much to their liking, they recruit and train someone to pose as the long lost Charlie. The man they've chosen however seems to know more about Charlie's childhood than they do.
