Arcam is a secret, worldwide organization investigating artifacts from a lost civilization. When three of their investigators go to Mt. Ararat, in Turkey, they discover what they believe is the wreck of Noah`s Ark. Their joy is short-lived, and so are they-the relic projects a powerful, destructive energy which wipes out not only the team but three Pentagon satellites as well. Quickly, Arcam and the US military are battling for the Ark`s secret. Arcam`s trump card is their super-powered warrior agents, called Spriggans. One Spriggan, a high school student named Yu Ominae is dragged into the fray. He makes his way to Turkey to confront the Pentagon`s platoons. Of course, the Americans have super-soldiers of their own, including the human tank Fat-Man and the vicious Little Boy. The bullets are soon flying en masse, in what has become a holy war for the future of the human species.
