Documents a high-tech fire-and-brimstone sermon that a Dallas Pentecostal church puts on every Halloween to scare kids into coming to services. Trinty Assembly of God church invented Hell Houses in 1990 and every Halloween since they've pulled out truckloads of lights, enlisted hundreds of actors and built an enormous haunted house complex from scratch. Trinty's Hell House looks to be just a souped-up haunted house until one enters. Inside, a tour guide dressed as a demon takes a group of kids from room to room to view depictions of school massacres, AIDS deaths, fatal drunk-driving crashes and botched abortions. All the while, demons goad gullible teen actors to commit sins and then drag their recently departed souls off to Hell. In the end, the audience is escorted to Hell to watch all of the sinners from Hell House burning and suffering and begging anyone who will listen not to make the same mistakes they made.
