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.
