Chase and August are at August's gym, where they are volunteering their time to help keep kids off the street and out of gangs. In the boxing ring is Andre, a young fighter determined to stay away from gang violence. But when word comes in that Andre's brother has been shot and killed by a rival gang, Andre swears to avenge his brother's death. Chase and August try to persuade him to let the police handle it, but Andre slips from their grasp in pursuit of the killer. The incident also brings back memories for Chase, who is struggling with unresolved guilt over his former partner's murder by a gang youth.

After a car chase with police, young Joey Morello, brother of a New York crime boss, barricades himself within a road-side burger stand, takes hostages, and demands a bus, plane, and money for an escape. Chase gains Joey's trust and talks some sense into the young man, getting him to drop his weapon. But when the cook panics and tries to escape, Joey is startled and draws an ankle-gun, and Chase is forced to shoot. The young kid dies, and his crime boss brother arrives in L.A. looking for revenge. Meanwhile, Chase is targeted by an Internal Affairs officer who is convinced he shot the young man for no reason because the kid's ankle-gun could not be found.
