Los Angeles, 1949. Ruthless mob king Mickey Cohen runs the show in this town, reaping the ill-gotten gains from the drugs, guns, 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 who are under his control. It's enough to intimidate even the bravest, street-hardened cop, except for the small, secret crew of LAPD outsiders who come together to try and tear Cohen's world apart.
