Raymond "Shrimp Boy" Chow is a survivor in the gangland of San Francisco's Chinatown. In 1976, the 16-year-old moved to San Francisco with his family and quickly joined the Hop Sing Boys gang. On September 4, 1977, he was at the Golden Dragon restaurant when 3 Joe Boys gang members killed 5 innocent patrons after storming the popular restaurant looking for revenge against their rivals, the Wah Ching.

Through the 1980's, Chicago's most powerful street gang expanded at an unprecedented rate, with its membership eventually numbering some 30,000. When the city of Chicago wasn't enough territory, the gang spread to other cities throughout the Midwest, like Milwaukee. The GDs quickly gained control of smaller towns using the tried and true methods of fear, intimidation and violence. When the crack-cocaine epidemic hit, the Gangster Disciples were ready to take full advantage. The GD organization operated much like a Fortune 500 company, raking in profits estimated at one hundred-million dollars a year. In 1995, however, everything changed. A federal indictment took down 40 leaders of the Gangster Disciples, including the Chairman of the Board, Larry Hoover. After that, it was every man for himself. Through the eyes of Gangster Disciples we watch the rise and fall of a drug empire as greed and violence wash over an army of Gangsters.

Throughout the early 1990's, a war waged behind the scenes between the two largest motorcycle gangs in America - the Outlaws and the Hells Angels. The Outlaws traditionally made the Midwest their stronghold but now the Angels were pushing into their territory and courting another regional club, the Hell's Henchmen, to join them. The Outlaws responded viscously and decisively. By the time the war ended bikers from all three clubs had been murdered and the third largest car bomb in US history had exploded on a crowded Chicago street during rush hour. Federal and local law enforcement began vigorously pursuing the Outlaws culminating in successful prosecutions that exposed the violent world of these notorious 1%er's. Within a decade, two international presidents would be serving life sentences and Outlaws members could be found on both the FBI and ATF's most wanted sites. For a while, it seemed the Outlaws Motorcycle Club would fade from relevance but recent arrests this year - and continuing investigations - show that they are still functioning and once again expanding their influence through blood and violence around the world.
