It's the ultimate nightmare for every child: eight-year-old Peter (Woody Norman) is woken from his sleep every night by an eerie knocking behind the walls of his room. However, his parents (Lizzy Caplan and Antony Starr) claim that he is only imagining the strange noises. Only his class teacher (Cleopatra Coleman) seems to believe Peter and tries to encourage him. When the frightened boy begins to get to the bottom of the origin of the knocking, he discovers that his parents are hiding a terrible secret from him.
