On Halloween night, the abandoned house on the corner of Maple Street lights up with eerie orange hues, beckoning the neighborhood children to come closer. Frank M. Kirby, Timothy Wall, and Irene Sanders, three brave teenagers, answer the call, but they never return home. The house is known as the House of Halloween, a place where no one dares to tread. But when the candy left outside isn't enough, the trio decides to venture inside, and that's when things take a turn for the worse.

The house has been vacant for a decade, ever since the family that lived there vanished without a trace. A mother, father, and their ten-year-old son disappeared into thin air. The neighborhood kids whisper about what might have happened to them, but no one knows for sure. The house looks abandoned most of the year, but on Halloween night, it comes alive with ghostly apparitions and spooky sound effects. The kids think it's all part of the show until they realize they can't get out.

Frank, Timothy, and Irene find themselves trapped in a maze of dark hallways and ominous rooms. They hear voices that don't belong to them and see things that can't be explained. As they search for a way out, they stumble upon the family that vanished years ago. But they're not alive – they're ghosts. The teens are shocked but soon realize that they're not alone in the house. An evil ghost named Faang has taken over and turned the family into unwilling spirits.
