What should have been a fun evening of trick or treating turns into a nightmare for Mumfry. He finds himself alone in a haunted house, but he is more worried about the bullies who lead him into the house than he is of ghosts. Things only get worse when he realizes he's not alone in the deserted mansion and barely escapes with his life. However, curiousity peaked and throwing caution to the wind, Mumfry convinces his friends to help him figure out the mystery he has stumbled onto. Just when they think they are safe, they run into a stranger in the park, Mumfry finds himself face to face with the intruder who was in the house, and the cops are after him for breaking and entering. Can Mumfry find a way out of the mess he's in or will the situation spell disaster for the group of friends?
