Having fallen into a difficult life situation, Beth comes to Los Angeles to visit her older sister, Ellie. Upon arrival, she discovers that her husband has left her, leaving them with three children. Their apartment complex is about to be demolished, and a new home has yet to be found. Deciding to talk to her sister alone, Ellie sends the children out for pizza. On the way back, they experience an earthquake, a sinkhole opens in the parking lot, and the older Danny discovers an ancient, mysterious tome and records. Out of curiosity, he opens the book and listens to the records, unleashing evil forces that immediately possess his mother and will now try to drag everyone present, especially the children, to hell.
