A young woman (Famke Janssen) is granted early release from her prison sentence for manslaughter (killing her husband a violent NYC cop in self defense) on condition she wear an electronic ankle bracelet and remain within her home, effectively under house arrest, for the remainder of her sentence. Her late husbands partner keeps tabs on her from a patrol car parked across the street, hoping shell violate probation and he can send her back to prison. But the 100-foot radius her ankle bracelet allows isnt the worst of her problems. Her dead husband --now a malevolent ghost--is still in the house, where he died -- intent on savage revenge.
