The TV series "Oz" tells the story of the lives of prisoners and staff in a state correctional facility. "Oz" is not a fairyland, but rather the Oswald Maximum Security Penitentiary. And the "Emerald City" is an experimental unit for inmates, where strict hierarchical relationships are established. Here, robbers and murderers, maniacs and sociopaths, drug addicts and homosexuals are incarcerated. Each of them knows their place and does everything possible to wake up alive in the morning.
