Four years after Finn killed his abductor and escaped as The Grabber`s sole survivor, the phone is ringing again. Now 17, Finn struggles with life after captivity while The Grabber seeks vengeance from beyond the grave, targeting his 15-year-old sister Gwen. She receives calls through the black phone in her dreams and visions of three boys stalked at Alpine Lake winter camp. To end the torment, Gwen and Finn visit the camp where they uncover a connection between The Grabber and their family. Together, they must confront a killer grown more powerful in death-and more significant than either imagined.
