Four teenagers go looking for a legendary haunted house that gives you money back for every floor you can complete. Once finding it, they realize the house is much more terrifying than a normal Halloween attraction - the house knows each of their secrets and one by one uses them against the teens.—Anonymous

It's a story that has existed throughout the Midwest for years - a haunted attraction that repays a portion of the admittance fee for every floor patrons are brave enough to complete. The haunted house is supposedly so terrifying, however, that nobody has ever made it all the way through to the end. On Halloween night, four Wisconsin teenagers go looking for this supposed urban legend. What they find is the House of Purgatory - the source of all the stories. Once inside the house, the teens quickly realize the house is more than a mere haunted attraction. The house somehow knows the things each of the kids keep hidden, and forces each of them to come face to face with the secrets they keep.—Tyler Christensen
