In 1949, Los Angeles. Brooklyn-born ruthless mob king Mickey Cohen (Sean Penn) runs the show in this town, reaping the ill-gotten gains from the drugs, guns and prostitutes--and if he has his way--every wire bet placed west of Chicago. And he does it all while having the protection of paid goons, the police and even politicians under his thumb. It's enough to intimidate even the bravest, street-hardened cop. Except for the few in a secret crew of the LAPD led by Sgt. John O'Mara (Josh Brolin) and Jerry Wooters (Ryan Gosling), who come together to try and tear Cohen's world apart. 'The Gangster Squad' is a colorful retelling of events involving the LAPD's efforts to take back the mean streets from one the most dangerous mafia bosses of all time.
'Gangster Squad' is scheduled for release on September 25, 2012.
