Behind the seemingly perfect Harper household, Greg (Jon Tenney, True Detective), the lead investigator of a child abduction case, is struggling to come to terms with the recent infidelity of his wife Jackie (Academy Award® winner Helen Hunt, As Good As It Gets). The already strained family harmony is further threatened when Connor (Judah Lewis, The Babysitter), their son, appears to be the victim of a mysterious malevolent presence in their house. As the secrets start to unravel, the plot threads prove to be more interlinked than it would appear at first glance.
