Nate Shaw can see and speak to ghosts. This means he’s seen talking to himself frequently giving him the label as freak at school. Even some of his family have cast him aside because of his ability.
Then walks in James. James is new to the school and Nate has been instructed to show him the ropes. The two quickly build a friendship. Only, James has an entity stuck to him, the reason he’s moved to Nate’s little town. Plus, James is on a mission, and Nate knows all the answers from his ghostly conversations.
