Louis Theroux concludes his exploration into Miami Mega-jail, one of America's largest and most violent of jails, a holding pen for almost 6000 un-convicted inmates. 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.
