Someone is taking New York's children. The police assume they know who the predator is, but an overzealous detective and a lieutenant over his head allow a serial killer to walk free. When the FBI sends profiler Scarlett Bell to catch the murderer, the deputy director demands she investigates the case alone. No partner to help solve the mystery. No one to watch her back. Except she has a secret weapon: fugitive killer Logan Wolf. Sensing the deputy director is setting Bell up, Agent Neil Gardy secretly follows his old partner, intent on keeping her safe from Logan Wolf. To catch a child murderer, Bell must go rogue and avoid police detection. But can she stop Gardy and Wolf from killing each other?
