In chasing devils, all roads lead to Hell.

1967: A brutal murder occurs at the Weston State Hospital in West Virginia. To amateur exorcist, Merle Blatty, this shocking story rings of the occult. Fueled by a desire to avenge the deaths of his wife and son, Merle investigates the case, unknowingly stepping into a sinister web spanning decades.

1997: It's been three years since the Hill family left the nightmares of the farm behind them. Alice is off to college while Daniel and Nora are closer than ever, living in Ohio and raising their three-year-old daughter, Maren. Their high hopes for the future are quickly extinguished when they receive a call, learning of a plan by Adam, Daniel's brother, to purchase the exorcist's former property and stage an Amityville-inspired haunting to profit from the story.

By alternating past and present narratives, The Exorcist's House: Genesis is a multi-generational odyssey through Hell, giving birth to a new breed of horror.
