Forensic sculptor Eve Duncan knows what it's like to be haunted by the past. For years after her daughter, Bonnie, was stolen from her, she fought for closure. When her mother, Sandra, asks Eve to find a missing friend named Beth Avery, she wants to help but is sure that Sandra is hiding something. The fact that she adamantly refuses to go to the police reinforces Eve's suspicions that something is very wrong. Eve learns that Beth has been locked away in a mental hospital for years, which makes it even harder to understand how she could have disappeared. As Sandra reluctantly reveals small pieces of the truth about Beth's identity, Eve is shocked to discover that their lives are strangely entwined, and Beth's disappearance now puts them all in grave danger.
