Duke and Earl are just passing through when they stop at a Gil's for a quick bite to eat. They aren't planning to stick around - until Loretta, the eatery's owner, offers them one hundred dollars to take care of her zombie problem. Given that Duke is a werewolf and Earl's a vampire, this should be easy money. But the shambling dead are just the tip of the iceberg. Seems someone's out to drive Loretta from the diner and is more than willing to raise a little hell on earth if that's what it takes. Duke and Earl suddenly find themselves facing such otherwordly complications as undead cattle, an amorous ghost, a jailbait sorceress, and the terrifying occult power of pig Latin.
