Los Angeles, 1949. Brooklyn native Mickey Cohen is a ruthless mafia godfather who runs the city and collects the ill-gotten goods of drugs, guns, prostitutes and - if he gets to his ends - everyone. betting west of Chicago. All this is made possible by the protection, not only of the henchmen on his payroll, but also of the police and politicians who are under his cup. That's enough to intimidate the bravest and toughest cops ... except, perhaps, the members of the small unofficial LAPD brigade led by Sergeants John O'Mara and Jerry Wooters who, together, will try to destroy Cohen's empire.
