From master-of-terror Brian De Palma comes this stylish psychological thriller that will keep you on the edge of your seat until the final frame. Carter Nix (John Lithgow) is a respected psychologist, loving husband and devoted father who decides to take a year off to help raise his daughter. Carter's wife Jenny (Lolita Davidovich) is pleased to have her attentive husband home at first. When Carter shows obsessive behavior toward their daughter, Jenny becomes concerned, and to complicate matters, Jenny's old flame (Steven Bauer) re-enters her life. But nothing can prepare her for the emergence of Carter's multiple personalities, and a fiendish plot to recreate the infamous experiments of his deranged father. It all adds up to a roller coaster ride of heart-pounding suspense and stunning visuals in a film the New York Times calls 'a delirious thriller'.
