Henry has been here for a long time. In the house, existing as a shadow of what he once was. When a new family moves in he is forced to face things within himself and without.
At ten years old, Simon starts seeing ghosts - and one of them is him. After moving house, the visions stop; however, ten years later, Simon feels he will never be able to rest until he can go back to his childhood home to prove to himself once and for all, they were just in his head.
