I don’t know where the idea that Haunted Houses are supposed to be fun came from, but this movie will definitely disprove that myth. Hell Fest is a movie in which people go to a haunted house theme park and encounter a man in a mask who is actually murdering people.
At first it seems like a typical theme park: you sign a waiver, get the actors to try and break character and go on rides. But then the group realizes that everything is actually real.
