But when Dov and Chris make a grim discovery -- a missing girl's body, hidden in a deserted ravine -- all bets are off. Detective Luke Callaghan returns to oversee the homicide investigation, and soon realizes this might be the work of a serial killer. When they learn that Andy has been assaulted and Gail violently abducted following the call girl sting, the officers rally in a race against time to track down Gail's captor before it's too late. Following up on a simple lead, one officer ends up directly in the path of the killer. Will it end with the ultimate sacrifice?
