In August 2006, a "burglary" occurs at the home of Kristi (Sprague Grayden) and Daniel Rey (Brian Boland), trashing their house and leaving only their infant son Hunter's bedroom untouched. The only thing stolen is a necklace that Kristi's sister, Katie, gave to her. Martine, the Latin American family housekeeper and nanny, senses "evil spirits" in the house and burns sage to rid the house of them, and Daniel fires her for doing so. Kristi also believes that their home is haunted, and she and Katie talk about being tormented by a demon when they were children. Daniel, however, initially dismisses her claim despite footage of strange occurrences around the house. Daniel's daughter from a prior marriage, Ali (Molly Ephraim), begins investigating the mysterious happenings; she discovers that humans can make deals with demons for wealth or power by forfeiting the soul of their first-born son, but if the deal is not fulfilled, the demon will stick to the family until another son is born — Hunter was the first male to be born on Kristi's side since the 1930s.
