Two close friends grow up together, one as an airship more technologically advanced than any plane. The other the first submarine ever made altered to be more powerful than nuclear subs. They find themselves with clashing ideals and their personal war spills into the United States where an entire military base was helpless to stop them. Three soldiers stumble onto the airship and realize its captain is the only one capable of stopping the submarine. The soldiers want to help but the captain is determined to get them off his ship as soon as possible. While the captain of the airship wants to stop his friend, he is far from a hero being fully willing to allow an entire submarine crew to drown just to capture his friend. It does not help that he is the great-grandson of a madman who used this very same airship to destroy half the armies in the world. So the Americans have to ask themselves if they can really trust him.
