Devil Land has been the world's premiere horror-themed amusement park for over 50 years, home to the scariest ride ever created - The Devil's Due.

Family owned and operated by the reclusive creator, Arthur Dante, and his two children Samhain and Halloween, Devil Land is seeing some financial stress with low park attendance. Samhain wants Devil Land to expand its brand beyond the park gates, and a rejection from his father in tandem with a request to design a new ride for the park, lead Samhain to uncover the sinister secrets of the park and the role his family, including his sister, has played in a myriad of unsolved deaths and disappearances at the park over the last 50 years.
