After their nan accidentally burns their home down, twin brothers Pat and Dom must move with their parents and baby sister to the seaside cottage they've summered in, now made desolate by the winter wind. It's there that the ghost appears -- a strange boy who cries black tears and fears a bad man, a soldier, who is chasing him. Soon Dom has become not-Dom, and Pat can sense that his brother is going to die -- while their overwhelmed parents can't even see what's happening.
