Finn is already 17 and is still trying to put his life back together after being kidnapped. Meanwhile, his sister Gwen starts receiving calls from a black phone in her dreams and sees disturbing visions of three boys being followed by a stranger at the winter camp "Alpine Lake." Deciding to solve this mystery and put an end to the torment - both hers and her brother's - Gwen convinces Finn to go to the camp during a winter blizzard. Now they have to confront a killer who, after death, became even stronger - and much more important to both of them than they imagined.
