Gangster Squad (2013)

In the year 1949, Los Angeles finds itself under the iron-fisted rule of Mickey Cohen, a ruthless mob boss hailing from Brooklyn. Profiting from the underworld's vices — drugs, firearms, and illicit gambling — Cohen's influence extends far and wide, with ambitions to dominate all illicit betting operations beyond Chicago. His empire thrives under the shield of corrupt law enforcement and politicians who dance to his tune. Even the most fearless police officers quiver in his shadow, except for a covert band of LAPD misfits led by Sgt. John O'Mara and Jerry Wooters. Together, they conspire to dismantle Cohen's criminal dominion from within.
