With Traci at the helm, 15 Division gears up for today’s raid: the target is a notorious gun dealer scheduled to receive a shipment in a few hours. But when Traci gets called away to Leo’s school and then goes off the grid, no one can believe that she would miss her first raid. They fear that Thom Kozik, the ruthless gun dealer, might be to blame for her disappearance. It’s all hands on deck when Andy and Gail realize that the serial rapist that got away from us (Ep. 512) is back – and he’s got Traci. As 15 Division works furiously with the Sex Crimes Unit to track down the suspect, Traci is trapped with her captor, using everything she knows as a cop to figure out who he is and fight her own way out.
