If you asked Britt Wheeler to tell you five things she hated, theme parks would be at the top of her list. She wouldn't tell you why should you ask, all she knows is that she hates them and that's that. Which is why she's more than dismayed when she and her group of amateur filmmakers select the long-abandoned theme park, Wonderworld, as the next topic in their documentary about obscure haunted locations. Word from an old local informs the kids that the place is haunted by the ghost of a teenage girl who was killed there long ago, alongside the ghosts of the former owners, who ended up being killed a few years later. Upon arriving, the group discovers that there is indeed some kind of activity going on... just not anything paranormal. Instead, a deranged serial killer has taken residency within the park's lower storage areas and is now very much intent on not letting his uninvited guests make it out in one piece.
