The story revolves around a struggle to determine which of Satan's (Harvey Keitel) three sons will succeed their father as ruler of Hell. Adrian (Rhys Ifans) is the most intelligent, Cassius (Tom Lister Jr.) is the toughest, and Nicky (Adam Sandler) is their father's favorite, even though Nicky has had a speech impediment and a disfigured jaw since Cassius hit him in the face with a shovel. Furthermore, Adrian and Cassius enjoy tormenting Nicky by claiming that his mother was a goat and assault him by controlling his body with their minds.
