Louis Theroux: Miami Mega-Jail

Louis spends time in one of the most notorious sections of Miami County Jail: the fifth and sixth floor of 'Main Jail', where many of the most volatile inmates are incarcerated. Held in large cage-like dwellings for up to 24 men, the inmates have developed a strange and violent jail culture. The men - who remain in the cells almost all the time and may only leave for yard time twice a week - live under the sway of a gladiatorial code. They fight each other for food, for status, and often just to pass the endless hours of confinement. Trips to the infirmary are a frequent occurrence as inmates are viciously attacked and beaten, but the guards say they are powerless to end the abuse.

Louis goes deeper into the jail system, meeting an alleged triple murderer facing a possible death sentence. He also follows a group of forty or so younger inmates who have escaped prison by pleading guilty and agreeing to attend a four-month military-style boot camp. Among them is a 14-year-old boy facing a possible ten-year sentence for armed robbery if he can't survive the boot camp's relentless and brutal training and indoctrination programme. Many will drop out and receive prison sentences, but for a handful this will be their second chance at life.
