Mid-century Los Angeles. Behind the public image of the Dragnet-era LAPD lay a hidden world of “pleasure girls,” crooked cops, ruthless newspaper tycoons, corrupt politicians, and East Coast gangsters on the make. Into this underworld came two men: L.A.'s most notorious gangster, Mickey Cohen, and its most famous police chief, William H. Parker, each prepared to battle the other for the soul of the city. The decades-long entanglement of these two kingpins shaped modern American policing and helped create the Los Angeles we know today.
