A true-crime writer (Ethan Hawke) moves into a new house, the scene of a horrific murder, though he doesn't tell his wife they have moved into the place. He gets his inspiration from the places he writes about--and it's been a while since he's had a best seller. He eventually discovers that a demon, which exists in images, is responsible and this particular demon feeds on the souls of children. The movie is along the lines of Insidious, a very effective horror film that builds to its climax. It's also an excellent example of how a film score can make or break a movie.
