The name on the street is OZ, but the name on the wall is the Oswald Maximum Security Penitentiary - or it was.  Now it's been changed to Oswald State Correctional Facility.  Maybe by getting rid of the word "penitentiary," the state is finally admitting that nobody's penitent.  Nobody's sorry.  NOBODY.

In the third explosive season, old scores are settled, new alliances are forged and tempers flare as hot as ever.

Oz... The 3rd Season

Oz, as in Oswald Maximum Security Penitentiary, an original series on HBO,follows a slew of characters incarcerated in a pod called Em or Emerald city, a unit run by Tim Mc Manus,and warden Leo Glenn. Unit is actually run by the inmates,Africans, Muslims,Latinos, Italians and Aryans all jockey for control of the drug trade & total control of the unit. Produced by Tom Fontana and starring Ernie Hudson, Terry Kinney, Rita Moreno,J.K. Simmons & B.D. Wong. An excellent series on life in a correctional facility. I watched this on HBO when it originally aired, gripping series. A must have to any collection, sex, violence, action, back-stabbing & betrayal. Not for the timid, uptight or children. Suggest you start at the beginning Season 1 to get the full story.
