Handsome pastor David Poe (Adrian Pasdar) and his psychologist wife, Clare (Cady McClain), have just relocated to Upstate New York with their young children, twins Jack (Austin Williams) and Emily (Amber Joy Williams). When Halloween inspires bizarre behavior in the twins, the Poes begin documenting their struggle to regain control over the children as their idyllic family life is torn apart by sociopathic -- and increasingly violent -- behavior.
