With the Strike Team laboring under suspicions about their role in the Money Train Heist, the hijacking of a truckload of ammunition draws Vic into a bloody race war between black and Latino gangs. As Vic works to keep Farmington from exploding, the botched arrest of an Asian gangster kills two innocent children and sends the normally complacent Korean community into the streets to vent their anger. Inside the Barn, politics and rivalries cloud the Strike Team's future and sidetrack Claudette's promotion, while Aceveda's marriage and City Council campaign are jeopardized by his humiliating sexual assault at the hands of a brutal gang. And as Dutch's investigations put him on the trail of an elusive rapist and expose a murdered public defender's drug addiction, autism threatens to rupture the Mackey family and Shane fights to conceal his role in a car accident that left a fellow cop in a coma.
