Adam and his wife Beth are a struggling couple with a newborn baby Emma. Adam receives a phone call from his estranged brother, Jake, informing him that their mother has gone missing. He urges Adam and his family to come back to their hometown. They are greeted by Jake and his wife Christy, who are a shining example of a happy couple. A search committee is at Evette's house, from “Gateways”, a bereavement group that has been helping Evette deal with the loss of her previous home and their father. As the brothers try to get past old grievances and work together in finding their mother, Adam becomes increasingly aware that Gateways may be up to something more sinister, and perhaps even behind their mother's disappearance. A dark, shadowy presence begins to stalk Beth, seeming to influence her thoughts. As Adam's paranoia continues to grow, he becomes terrified that Gateways and a shapeless, faceless creature lurking around the family may be after their newborn baby.
