In a chilling tale of psychological terror, Barbara Hershey stars as Carla Moran, a single mother whose life is shattered by a series of brutal, unseen attacks in her own home. Directed by Sidney J. Furie, this harrowing horror film follows Carla as she desperately seeks help, turning to a team of skeptical parapsychologists led by the pragmatic Dr. Phil Sneiderman, played by Ron Silver. As the violent phenomena escalate with terrifying intensity, the investigators must confront the possibility of a malevolent, non-human entity with a singular and horrifying fixation on Carla. Based on a controversial real-life case, the film masterfully builds an atmosphere of relentless dread, blurring the lines between psychological trauma and supernatural horror as Carla fights not just for her sanity, but for her very survival against an invisible, predatory force.
