Inside ADX Florence, America's most notorious federal supermax prison, some of the country's most infamous gang leaders have faced decades behind the most restrictive prison walls in the federal system. But what crimes brought them there, how did they build their criminal empires, and what finally happened when federal investigators came after them?

In this gripping true-crime prison documentary, we examine the stories of 7 Black gang leaders whose criminal cases became connected to ADX Supermax. From the Gangster Disciples in Chicago to the Supreme Team in Queens, these cases reveal the disturbing realities of organized crime, drug trafficking, racketeering, murder-for-hire, witness intimidation, and the federal investigations that brought powerful criminal organizations under scrutiny.

Meet Larry Hoover, the founder of the Gangster Disciples; Jeff Fort, the Chicago gang leader convicted in a conspiracy involving Libya; Omar “O.G. Mack” Portee, associated with the founding of the United Blood Nation; Kaboni Savage, the Philadelphia drug trafficker convicted of multiple murders; Ronald “Ra Diggs” Herron, the Brooklyn gang leader convicted of racketeering and murder; Kenneth “Supreme” McGriff, the founder of the Supreme Team; and Dwight York, the leader of the Nuwaubian movement convicted of serious federal offenses.

Each case reveals a different side of America's criminal underworld. Through documented crimes, federal prosecutions, courtroom evidence, convictions, and prison histories, this documentary explores how these men rose to prominence, how investigators built their cases, and why their names became associated with some of the most restrictive conditions in the American prison system.

But there is an important distinction: not everyone featured in this documentary remains at ADX Florence today. Some were transferred, and others experienced significant changes in their legal circumstances. This documentary examines their documented connections to ADX rather than claiming that all seven are currently held there.

Which of these cases shocked you the most? Do you believe America's toughest prisons can permanently dismantle criminal organizations, or can a gang's influence survive long after its leader is locked away? Share your thoughts in the comments.
