Los Angeles, 1949. Ruthless, Brooklyn-born mob king Mickey Cohen runs the show in this town, reaping the ill-gotten gains from the drugs, the guns, the prostitutes and if he has his way, every wire bet placed west of Chicago. And he does it all with the protection of not only his own paid goons, but also the police and the politicians he has under his thumb. It's enough to intimidate even the bravest, street-hardened cop except, perhaps, for the small, secret crew of LAPD outsiders led by Sgt. John O'Mara and Sgt. Jerry Wooters, who come together to try to tear Cohen's world apart. Under the direction of Ruben Fleischer, Gangster Squad is a stylish retelling of events surrounding the LAPD's efforts to take back their nascent city from one of the most dangerous mafia bosses of all time.
