A down-on-his-luck schlub is possessed by a malevolent demon . . .Just when he thinks things can't get worse, the exorcism goes wrong . . . and he finds that somehow he's retained all of the entity's supernatural gifts. After a path of revenge on all the people that have wronged him, he begins to gather worshippers and form a cult. But the legions of Hell don't take kindly to this, and they send demonic agents to murder the schlub-turned-god before he gains too much power.
