Stan knows every inch of Hilltop Cemetery. But when he ventures toward an area of old graves for the first time, he feels pushed back, as if he's being repelled by an unseen force. He writes a blog post about it and is surprised to find two anonymous comments. One warns him to stay away from the graveyard, the other begs for help! After a few visits to the cemetery to check out the strange energy, Stan discovers that a little ghost girl is trapped inside the evil force field. Can Stan and the Zombie Hunters find a way to rescue the girl, even if it means they might get suck inside the force field themselves?
