When Jonah discovers Maldeus is working with the asylum doctor to sacrifice women on a giant pentagram, he's thrust into the middle of a diabolic plot involving occult magic, invisible people, and a perverted, sex-crazed blue demon! Will he keep his wits about him as he pretends to be Maldeus and stop the rise of Satan?
