An investigation into Goergen's death starts and Mobay's anxious when the investigator targets him first. Tensions begin to rise as Querns turns a seemingly deaf ear and blind eye to the blatant violations committed by black inmates. An inmate transfer works in Adebisi's favor. Arif challenges Querns's authority. Ginzburg's poor health forces him to request an early execution and Sister Pete convinces Glynn to make it happen. Glynn's press conference announcement forces his daughter to make a major decision. Beecher's daughter arrives alive and Keller confesses to Mukada.

Ryan and Howell get frisky. After leaving the hole and apologizing to Busmalis for the stabbing Rebadow suffers an attack due to a brain tumor. Busmalis reacts by doing what he does best--start another tunnel. Unbeknownst to the doctors and everyone else, Cyril's recovering psychologically more than he can actually show. Arif confesses to Said about his own demons and asks for forgiveness and help. Said plots with McManus to end Querns' and Adebisi's control. Hank Schillinger beats the kidnapping rap and once Beecher finds out, he plots with Pancamo for revenge. After Keller reveals his plot to kill him, Eli Zabitz asks Schillinger for protection. Schillinger agrees but sends Robson to eliminate Zabitz instead. Hughes, now raging beyond sensibility, makes an attempt on Devlin's life at a press conference. Keller and Father Ray have an intense discussion about Beecher.

After the press conference shooting incident, Glynn pulls out of the race. When a corpse is found in the laundry room, Querns demands Adebisi find out who did the deed. Soon Browne's corpse is also discovered and Querns gets worried. Querns's investigative efforts point to Supreme Allah as the culprit only Supreme's really being framed for the two killings by O'Reily and Keller. Hill pays big when he tells Mobay he knows he's undercover and Mobay comes clean about his involvement in Oz's recent crimes. Considering the words of Cyril, Sister Pete decides to remain in the Order. On death row, Deyell delivers some payback after Miles goes on another racist tirade. Vern finds out he's going to be a grandfather. Said moves in with Adebisi in order to get some proof of Adebisi's rowdy behavior. Simon finds out and delivers a tape of one of Adebisi's "parties" to Said hoping to "gain his trust" as a "brother" Said turns the evidence over to McManus. The result? Querns gets fired, McManus is reinstated and Adebisi and his cronies get moved to Unit B. Enraged about these new developments, Adebisi and Said struggle in the pod and one of them becomes Oz's latest murder victim.

Glynn receives some good and bad news on the toxic-poisoning case. Meanwhile, Rebadow's relationship with Stella hits a snag; Keller and Beecher work out a mutually beneficial arrangement; Poet and Redding nearly come to blows; Hoyt is transferred from Death Row; and Robson finally gets some redemption.

Everyone has a different opinion of new inmate Idzik; Alvarez receives shocking news; Redding's attempts at reform continue; Murphy makes a confession to Glynn; Morales'(David Zayas) medical suspicions are confirmed; and Beecher's devotion to Keller leads him into a perilous position.
