Inside The Gangsters' Code documentary series directed by Kim Flitcroft, packaged on DVD.

In this compelling series from Discovery, ex-Mafia insider Lou Ferrente goes Inside the Gangsters Code and reveals the untold secrets of the world's hidden leaders: gangsters whose international reach and power has grown to epic levels. Having served almost 10 years in maximum security prisons across the USA, Lou uses his insider knowledge to dig deep into the epicentre of gang culture and organised crime, exploring their influence on the world's most dangerous streets and inside the worlds' most notorious prisons. From El Savador and the Philippines to Italy and Poland, Lou sets out to investigate the origins of these prison gangs, delving into their history, networks of command, motivations and political sway in forensic detail, with an insight and passion never before applied to the subject. Fully immersing himself in the culture of each gang, both inside and outside prison, Lou lives alongside inmates, talks to guards and gets under the skin of gang members, before coming face to face with the top soldiers and gang bosses who reign over these dangerous and powerful organisations. Will Lou's experience help him, or is he in way over his head?
