Wendell and Wild are the scheming demonic brothers trapped in the world of the dead. Working tirelessly for Buffalo Belzer, the duo is desperate to deliver themselves from the murky underworld and appear fully formed in the land of the living. Striking into the dreamscape of a young Kat, a grief-ridden teen at a repressive boarding school, the trio enters a bargain that will see them tied together for a wild adventure through life and death. As Wendell and Wild personify Kat’s demons, the hard-nosed and angry teen must face her sorrow in the ghost land of her hometown, that since her parents' death, has become as sullen and empty as the goth teen herself. Between her only real friend Raul and the mysterious nun Helley, Kat has only a few possible allies in the hellish happening she’s mixed up in. Wendell and Wild meanwhile are looking to get out from under the thumb of their satanic father and whether she knows it or not, Kat seems to have all the answers.
