The world as we know is about to change - the united forces of demons, gods, and monsters prepare for another deadly attempt to eradicate "the big guys" and change the religious status quo. And, just perhaps, to drink lots of tea and discuss art in the meantime. The only one who can stop them is Bonaventura Horowitz - a snarky exorcist, who isn't exactly an angel himself. At the request of the Pope himself, Bon, accompanied by a group of his peculiar friends, sets off on a thrilling mission, leaving behind a trail of cigarette butts, empty whiskey bottles, and broken demonic hearts.
