Thirteen-year-old Finney Blake is abducted by a sadistic killer. Held captive in a locked basement, Finney discovers a disconnected black rotary phone mounted to the wall. At first glance, it seems useless. But then the phone begins to ring. One by one, Finney begins receiving calls from the killer’s previous victims—boys who were once in his place and who didn’t survive. Their whispers echo through the line, offering fragments of advice, warnings and a chance at escape that may be Finney’s only hope.
