Japan, 1614 - The Tokugawa Shogunate bans Christianity and slaughters all of its practitioners. The survivors can only place their faith in the prophecy that a Child of Heaven will be born to deliver the faithful from their enemies. However, should that savior falter, he will be reborn as Satan. In Shiro Amakusa, the Christians believe they have found their savior, setting the stage for blood-soaked horror and treachery.
