Guy Wheatley is a successful lawyer at the helm of Seattle's most prominent law firm. He's at the height of his career until the day his wife disappears. Beth dropped their daughter at the daycare centre - and never picked her up. No one has seen her since. This is only the beginning of Gus's nightmare. Forced to admit that his busy career has distanced him from his own family, Gus must now help the FBI find out every possible detail about his wife's disappearance. Beth may be the latest victim of a vicious serial killer targeting Seattle. As the string of killings continue, the FBI's focus turns towards Gus's marriage and a string of peculiarities in Beth's behaviour. Lurking in the shadows, is a terrifying unknown - a chilling, charismatic cult leader who seems to have had more than a passing acquaintance with the woman Gus thought he knew well.
