Josh is a gamer. After his parents' divorce and his move from Chicago to a small town where he doesn't know anybody, he copes by staying up way too late playing Killswitch online. Then he discovers a "mod" version of the game that is an exact reproduction of his new town. And the virtual McCallum High School has been populated with figures that look remarkably familiar. Strange things start to happen in the game, and they are somehow connected with events in the real world. Josh soon learns that the virtual Valleytown was created as a revenge training ground and has to figure out the creator's true identity before someone in the real world gets hurt.
