In the 'Emerald City' experimental unit of Oswald State Penitentiary, we meet some of the diverse inmates who exist in a pecking order of Gangbangers, Latinos, Muslims, Westies, Aryans and Wiseguys.

With Schibetta and the prison brass in a race to uncover Ortolani's killer, we see how inmates react to visits both from their wives and, family members who are also in prison.

Friction is growing in the wake of two deaths so Said, Wiseguy leader Schibetta and Gangbanger Jefferson Keane are brought together by Warden Glynn, who tells them to keep their boys quiet or else he'll lock the prison down.

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 their skirmish.

Alvarez and Schillinger are let out of solitary and placed back in general population.
