HBO's controversial hit drama series continues, following the extremely violent way of life inside an experimental unit of the Oswald Maximum Security Prison (aka "Oz") as warring factions within the system constantly try to gain the upper hand. New prisoners in this frightful, gripping world include the sexually provocative child killer Shirley Bellinger and a guilty priest who'll be forced to pay a terrible penance.

This Emmy-nominated series from HBO was groundbreaking when it began, and continues to thrill in subsequent seasons. Emerald City, an experimental unit of the Oswald Maximum Security Prison, focuses on prisoner rehabilitation over public retribution. In this world, every gang has its mutual friends -- and mutual enemies -- and the third season sees animosity grow and relationships become more complex in the gritty world behind the prison walls.

Oswald State Penitentiary (aka "Oz") is in complete lockdown at the start of yet another gripping season of this shocking HBO drama series, and tensions are at their highest as Warden Leo Glynn (Ernie Hudson) tries to broker peace. In the meantime, Beecher (Lee Tergesen) and Keller (Christopher Meloni) have a difficult time keeping their liaison a secret, and the rest of the prisoners try to make a difficult existence that much more manageable.

The sixth and final season of HBO's groundbreaking series delivers everything fans of the show would expect. Oswald State Penitentiary has reached its boiling point, and none of its residents will escape unscathed. Add to the mix the intrigue of the inmates' preparation for a performance of "Macbeth," and the climax of this volatile series promises to be explosive. Special features include commentaries and deleted scenes.
