You and your family move next door to an empty, run-down house that your friends are sure is haunted. One day on your way home from school, you see someone knock on the door and go inside after the door is opened from the inside for him. Startled, you watch the house all night, but he doesn’t leave. The next day, you see another person approach the house, and the same thing happens. You and your friends decide to check it out. What do you find?
