Finney Blake, a shy but clever 13-year-old boy, is abducted by a sadistic killer and trapped in a soundproof basement where screaming is of little use. When a disconnected phone on the wall begins to ring, Finney discovers that he can hear the voices of the killer’s previous victims. And they are dead set on making sure that what happened to them doesn’t happen to Finney.

As Finn, now 17, struggles with life after his captivity, his sister begins receiving calls in her dreams from the black phone and seeing disturbing visions of three boys being stalked at a winter camp known as Alpine Lake.
