A volatile men-in-prison soap opera, fueled by testosterone and lubricated by blood, HBO's Oz is addictive viewing. The third season of the most violent show on cable TV, set in a cage of concrete and steel and glass, opens with echoes of violence past. Miguel Alvarez (Kirk Acevedo) is in solitary confinement for brutally blinding a guard, one-time drug lord Simon Adebissi (Adewale Akinnuoye-Agbaje) mourns for his murdered father, and Tobias Beecher (Lee Tergesen) nurses bones broken by Aryan Brotherhood leader Schillinger (J.K. Simmons) and a heart broken by the betrayal of Keller (Law and Order: SVU's Christopher Meloni). Their stories of vengeance, redemption, and forgiveness anchor this season.

The show races through each episode with a driving pace that only intensifies the ferocity. But for all the show's physical brutality, the most affecting violence is emotional, from the strange and savage love affair between Beecher and Keller to the escalating war of terror between Beecher and Schillinger. On a lighter note, this season marks the debut of both Miss Sally and new prison CO Sean Murphy (Robert Clohessy), whose understated strength is too often overlooked in the face of the show's more explosive personalities. Season 3 ends pitched on a powder keg, with the fuse in the hands of the show's most ferocious, unpredictable character. It's the kind of promise that will have you slavering for season 4.

The three-disc set features all eight episodes along with a season 2 recap, episode recaps and previews, commentary on the episode "Unnatural Disasters" by writer-creator Tom Fontana and episode director Chazz Palmintieri, and 22 minutes of deleted scenes.
