What would you do if you woke up in your home… but it wasn't your home at all? When a man wearing a picture mask of her daughter Maisie's face stands tauntingly in her garden, Lily Russell does the smart thing and calls the police. When she and Maisie wake up the following morning in an exact replica of their home, held captive by that same man, the police are no longer an option. Surrounded by the rooms and things that once provided comfort and now only promote fear, Lily and Maisie must fight to survive. Because when no one knows where you are, you are your only hope.
