Things have been difficult for Annie since her husband left; her teenage daughter, Isla, has become a ghost of her former self. Annie's terrified that Isla might hurt herself, and she'll lose her, too. So when Annie receives a video of herself crying at Isla's funeral, she's immediately sick to her stomach. Confused and horrified, Annie races upstairs to check on Isla, who is perfectly alive and well. The video has been faked. But who sent it and what do they want? One dark truth soon becomes clear: Isla will die for real if Annie doesn't give the sender the money they're looking for, or if she goes to the police. But Annie's not sure she has the cash, which leaves her with one choice: find the blackmailer and stop them in their tracks.
