Gangster Squad is the latest effort from director Ruben Fleischer (Zombieland) and focuses on corrupt and seedy 1949 Los Angeles. The main premise is that LA is run by the Brooklyn-born mob boss Mickey Cohen (Sean Penn), who has his fingers in various dirty pies — namely drugs, guns, prostitutes and gambling. How does Mickey get away with all of this? Why, he has the local police and politicians in his back pocket, of course.

Everything and everyone is under the control of Mickey — that is, apart from a small, secret, “off the books” crew of LAPD cops that plan on taking Mickey Cohen down. Leading the group are Sgt. John O’Mare (Josh Brolin) and Jerry Wooters (Ryan Gosling). Joining Penn, Brolin and Gosling, the strong ensemble cast also features Nick Nolte, Emma Stone, Robert Patrick, Anthony Mackie, Michael Pena and Giovanni Ribisi.
