In the final war between Heaven and Hell, pray he's on your side. When exorcism fails, the Church secretly sends for one man to finish the job: Jake Greyman. Jake knows the truth about the demons that walk our world and is free to slay their spawn at will. But when Satan unleashes a plan to impregnate young Los Angeles prostitutes with his evil seed, Jake must team up with an unorthodox young nun to save mankind from its own monstrous nature.
