After the riot . . . after the killings . . . after the lockdown . . . after the hate . . . there is one dream left for the Emerald City prisoners at Oswald State Penitentiary: the dream of escaping it — alive or dead. HBO presents Season 2 of this acclaimed drama series that focuses on an experimental "prison within a prison" called Emerald City, the site of a deadly riot climaxing the first season. Despite a renewed rehab commitment by its creator, Tim McManus, Em City and its congregation of colorful — and highly volatile — inmates remains steeped in corruption, violence and racism — as well as the desire among inmates to escape prison realities by any means necessary.
