An ancient story once thought to be the subject of legends becomes a horrifying truth for a man who must fight for his life to protect his last remaining kin. Along the way he must fend of creatures of darkness, particularly one who is a particularly formidable foe in the form of a demon from an alter plane. Not only is he fighting for his and his daughter's lives, he is fighting for the salvation of mankind's very existence. He's running out of time.
