In 1963, paranormal investigators and demonologists Lillian (Nicole Kidman) and Eric (Robert Downey Jr.) Warner are summoned to the home of Cadence (Julianne Moore) and Robert (Cary Elwes) Poland. The Polands and their five daughters have recently moved into a secluded farmhouse, where a supernatural presence has made itself known. Though the manifestations are relatively benign at first, events soon escalate in horrifying fashion, especially after the Warners discover the house's macabre history.
