In the "Emerald City" experimental unit of Oswald State Penitentiary, we meet some of the diverse inmates who live within a pecking order of Homeboys, Latinos, Muslims, Irish, Aryans, and Wiseguys. No clear-cut leader emerges -- with the possible exception of Kareem Said, a Muslim author who preaches non-violence and abstinence. Said's arrival doesn't prevent a short-fused Mafia inmate named Dino Ortolani from ticking off just about everybody--a habit that ends up burning him.
Friction grows in the wake of two deaths--first Ortoloni and now Johnny Post--so Wiseguy leader Schibetta, Muslim leader Said, and Homeboy Jefferson Keane are brought together by Warden Glynn, who tells them to keep their boys quiet or else he'll lock the prison down. The tension increases following a visit from Governor Devlin, who was responsible for the ban on smoking and conjugal visits. Meanwhile, Keane has found God--just as a couple of Latinos with a grudge find him.
Governor Devlin has reinstated capital punishment in the state; and the first Oz prisoner scheduled to die is Jefferson Keane, who killed a Latino in a skirmish set up by the Co's. Before he's executed, Keane donates a kidney to his ailing sister, then turns down lawyer-turned-inmate Tobias Beecher's offer to take up his defense. After Keane's death, Richard L'Italien -- slaughterer of women -- is executed by lethal injection after he makes a startling admission.
The infiltration of drugs into Oz has reached unprecedented levels; and the undercover efforts of McManus and Glynn to find out who's smuggling it in backfires in a deadly way. Despite a lockdown in the Emerald City, drugs continue to trickle in--and the blame shifts from prisoners to corrupt officials.
Three generations of Alvarezes--all prisoners at Oz--are united when the partiarch, Ricardo, is found face down in his cell, suffering from Alzheimer's disease. Meanwhile, Tobias Beecher, who as the neo-Nazi Schillinger's "girlfriend" has been forced to wear women's clothes, flips out after taking PCP and sends Schillinger to the hospital with an eye cut. Other inmates aren't exactly the picture of health, either. Mob boss Schibetta has stomach pains caused by ground glass intentionally mixed in with his food, and Muslim leader Kareem Said has a heart attack after refusing to take medication for high blood pressure.
A recovered Said ostracizes Huseni Mershah for turning his back on him when he was dying--and orders all the Muslims to cast him out. Impressed by Said's power, Groves decides to kill Glynn in his honor, but ends up stabbing and killing an officer by mistake. Condemned to death, Groves chooses the firing squad as his form of execution. Meanwhile, Schibetta is still being fed ground glass by O'Reilly and Adebisi, and ends up hemmorhaging. Beecher, transformed by prison life, finally gets revenge on his nemesis, Schillinger.
Beecher is released from the hole and Schillinger is left eyeless and weak. A riot breaks out after two white punks get into a fight over checkers. Frustration, sexuality, hate, revenge, racism all rear their ugly heads, causing the violence to escalate. Finally, after several prison officers are taken hostage, tear gas is thrown into the Emerald City and the SORT team arrives, guns blazing.
In the aftermath of the riot that killed six inmates and two officers, Oz is locked down, and Emerald City prisoners are sent either to solitary or "gen pop." A special committee is appointed to investigate the riot and Governor Devlin's handling of it. The committee's leader is law-school Dean Alvah Case, who roams Oz questioning inmates and officers alike. Inside a gen-pop prisoner named James Robson demands that Beecher perform oral sex on him, and gets a painful tip in return. Case determines that the death of inmate Scott Ross during the riot was no accident-but is the truth better left untold?
Ten months after the riot, Em City re-opens. A recovered McManus creates a council of group representatives to keep order, and initiates GED classes to help inmates get high-school equivalency diplomas. Having been told by O'Reily that Adebisi was responsible for his father's death, Peter Schibetta takes over the kitchen by cashing in a favor Glynn owes the family. As Schillinger's parole hearing nears, Beecher taunts his nemesis mercilessly in an attempt to ruin Schillinger's quest for freedom. Glynn's duaghter is raped by a group of Latinos, and the warden takes out his frustations on Alvarez. O'Reily learns he may have breast cancer.
Alvarez knows who raped Glynn's daughter, but refuses to tell the warden. Wangler is making progress at school, but his cellmate, Adebisi, isn't a fan of higher education. When Augustus Hill's judge is convicted of accepting bribes, Said takes up Hill's case to get him a second trial. Diagnosed with cancer, O'Reily goes to a hospital to get a prison-paid lumpectomy, which is cheaper than a mastectomy. The Aryans are losing credibility in Oz, so Schillinger arranges to have a tough named Vogel killed with Beecher being the next on the hit list. Finally, the prison is filled with excitement as a woman, Shirley Bellinger, arrives on death row to be executed.
Augustus Hill's court appeal is denied, despite the efforts of Said, who has better luck getting Poet's poems published. Meanwhile, O'Reily survives his lumpectomy, and now focuses his attention on Dr. Nathan. Trying to cut a deal after killing an Aryan inmate, Richie Hanlon is forced instead to admit to a murder he didn't commit. Schibetta offers Alvarez a piece of his drug biz in exchange for killing Adebisi. Beecher is forced to meet with the judge who sentenced him; it appears she has a guilty conscience. Beecher's new roommate, Chris Keller, seems to hate Aryans as much as Beecher but appearances can be misleading.
With their enmity at a boiling point, Adebisi poisons Schibetta -- but not fatally. Now that his brother has turned himself in for murder, Glynn no longer owes Schibetta any favors. Sister Peter Marie figures out that Giles witnessed who killed her husband. Poet, now a published author, gets his parole, but Governor Devlin still takes away funds from McManus's high-school equivalency program. When Beecher learns his wife committed suicide, Keller offers comfort, but his advances are rebuked. Meanwhile O'Reily is in love with Dr. Nathan, and gets his brother Cyril to have her husband killed.
Schilinger enlists Said to get him out of jail, but Said backs out. McManus decides not to incriminate Wittlesey in Ross's death. A recovered Schibetta edures more pain after being raped by Adebisi. Meanwhile, Alvarez is bumped out of the Latino power seat by Raoul Hernandez, a.k.a. El Cid. New inmate Jiggy Walker claims he was Gov. Devlin's personal crack dealer. The two go head-to-head in the media before Walker is discredited and sent to genpop. Reimondo finds out that Giles murdered the man who killed her husband and Dr. Nathan confronts O'Reily about her husband's death.

Alvarez gouges out Rivera's eyes and is put in solitary for life. Needing a blood transfusion for Rivera, Dr. Nathan finds that only O'Reily has the same blood type; he agrees to donate in exchange for getting his brother Cyril near him. Keller and Schillinger reveal their sordid plan of deceit to Beecher while breakingv both his arms and legs. Fortune teller Kipkemei Jara gives Adebisi hope of a new life; but he is murdered by Wangler on orders from Antonio Nappa. The grief this causes Adebisi lands him in the psych ward.

In addition to the name change to "Oswald State Correctional Facility," more changes abound. Newbies Coyle, Kahn, and Ricardo arrive and partner up with Wangler, Said, and Hernandez respectively.
