"A tourist flattened by a Hollywood tour bus. Rival gangs facing off at a drug dealer's funeral. Victims cooked by their killer. On their darkest, most dangerous days, this what LA's beat cops and detectives confront on the sunbaked streets of the Southland. And the fallout seeps into their personal lives--collateral damage from a 24/7 job that demands an arsenal of razor-sharp instincts and quicksilver reflexes. But even heroes need heroes, and when two cops are kidnapped, the entire department scrambles to save their own in an explosive series finale."
