L.A. Heat - Season 1 Episode 13 My Brother's Keeper

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.
