Here's an offer you won't want to refuse...Meet the men who make a living while making a killing: some of the most ruthless and notorious figures in the history of organised crime. It's a cut-throat business filled with crooks and criminals, and where danger constantly lurks in the form of police, rivals and even sometimes your closest allies. In this dog-eat-dog world, only those with something special rise to become the leader of the pack. These are their stories. Go back to the days of Chicago's gangland era and uncover the legends of Frank Nitti and Tony Big Tuna Accardo, two infamous mobsters who reigned over the Chicago Outfit in the wake of Al Capone s imprisonment and death. Witness the tale of Joey Gallo, who went from the slums of Brooklyn to the toast of New York's high society, only to meet an early and violent end. Explore the lives of Mob hitman Joseph 'Mad Dog' Sullivan and the Irish gang known as The Westies, before taking a grisly tour of the most notorious mafia killings of all time.
