A rich record executive (Affleck) stuck with spending Christmas alone (after his girlfriend, played by Morrison, dumps him) decides to return to the one place where he was once happiest, his childhood home, asking the family that lives there now to take him in for their holiday celebrations, but he discovers that his new "family" is even more psychopathic than his real kin. (Applegate plays the daughter of the family, an intelligent scientist; Gandolfini and O'Hara play the parents).
