It's Halloween and the teenagers from St. Rita's High School want to party at the neighborhood's haunted house. For years, the Hull House has sat in eerie silence – tales of its haunted past have turned into gory jokes and no one really believes anything ever happened there. However, Angela (Amelia Kinkade), the hostess from hell, is summoning her army of teen demons to the blood-curdling contest between the school's priests and herself, the princess of darkness. What was intended as an innocent evening of fun and games turns into a hell-raising, life-threatening ordeal ... they wanted fun, now they're in the trick-or-treat party of their lives!
