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.
OZ is set deep inside the Oswald Maximum Security Prison, in an experimental unit known as Emerald City. Em City focuses on prisoner rehabilitation over public retribution. There's one set of rules from the outside looking in, and another once you're inside. Every group - Muslims, Latinos, Italians, Aryans - stick close to their mutual friends and terrorizes their mutual enemies.
