Robert De Niro and Dakota Fanning send pulses racing in this "genuine scare-fest" (The Calgary Sun) that delivers terrifying twists and a shocking surprise ending.

At their new home in upstate New York, newly widowed psychologist David Callaway (DeNiro) tries desperately to help his traumatized daughter Emily (Fanning) deal with her mother's death. But before long, both David and Emily are being terrorized by someone - or something - named Charlie: a "friend" who may or may not be imaginary but is definitely the stuff nightmares are made of! Ready or not... "you'll be jumping out of your seat!" (Richard Roper)
