No names. No badges. No mercy.
The year is 1949 and ruthless gangster Mickey Cohen (Sean Penn) has the city of Los Angeles in his grip. Against a gang protected by rampant corruption, Chief Bill Parker (Nick Nolte) resorts to extremes. He enlists battle-hardened hero Sgt. John O'Mara (Josh Brolin) to form a unit to exact vigilante justice. Their job isn't to make arrests... it's to make war. As the city explodes in gunfire, jaded cop Sgt. Jerry Wooters (Ryan Gosling) is reluctantly drawn into the fight as he falls hard for Grace Faraday (Emma Stone), the elegant beauty whom Cohen claims as his own. Inspired by an incredible true story, Gangster Squad blows open the secret flies of the cops who fought for L.A.'s soul.
