Only he can stop the gates of Hell from opening wide.
John Crawford wasn't able to deal with the pain and took the easy way out. At least he thought he did. Instead, he's been offered a deal by a nightmarish creature and given a second chance at life. But he's no longer human. And he's been assigned an impossible task. He must kill a demon before it opens the gates of Hell and brings about the apocalypse. If John succeeds, the human race will be safe and he can become human again. If he fails, mankind will perish and he will be lost for all eternity.
