I'm trying to find the name of a fairly new movie. I saw previews on TV but don't remember the name or actors. It's a teenage boy who I think has been kidnapped and hidden away somewhere. Everyone thinks he's dead. His "ghost" comes back home and to school but no one can see or here him. He has to make someone see or hear him so they can find him before he dies. Finally one girl at school hears him. That's all I know. Can you help me?
