Inside San Quentin, gangs, drugs and sheer boredom make up a violent mix. In this program, you'll meet Scanvinski Hymes, who's been in prison since he was 18 years old. Now, almost 20 years later, he's racked up the highest number of violent offenses in California prison history. His favorite form of mayhem? Inciting cell extractions, a violent procedure where guards struggle to remove an inmate from his cell. Nevertheless, it's time for Hymes' release, and as he prepares for life on the outside, he faces the harsh reality that for most inmates, leaving prison is just a temporary freedom. Two years after getting out, more than 50% of prisoners find themselves right back behind bars.
