All that glitters is not Emerald City. Following the bloodbath that ended the prison riot, life is returning to far from normal for those who survived in the experimental unit of Oz. The Aryan Schillinger still butts heads with Beecher. The mob, led by Schibetta, continues to find its business cut into by the cold-hearted Adebisi. Warden Glynn and Tim McManus struggle to do the right thing for their prisoners, facing adversity at every turn from Governor Devlin. New prisoners include the sexually provocative child killer Shirley Bellinger and a guilty priest who will be forced to pay a terrible penance. The world of Oz will shatter your expectations in a new season where safety is not a option.
