Part one of two. The veteran broadcaster follows life inside two prisons holding some of America's most notorious female criminals - Indiana Women's Prison and Rockville Correctional Facility in the same US state. Among the inmates he meets in the first edition is Sarah Pender, who went on the run while serving 110 years for double murder, before being captured four months later, and Martha Search, who is looking forward to getting to grips with modern technology when her 20-year sentence comes to an end.
