In the first episode of this two-part series, Louis spends time in one of the most notorious sections of Miami County Jail: the fifth and sixth floor of 'Main Jail', where many of the most volatile inmates are incarcerated. Held in large cage-like dwellings for up to 24 men, the inmates have developed a strange and violent jail culture. The men - who remain in the cells almost all the time and may only leave for yard time twice a week - live under the sway of a gladiatorial code. They fight each other for food, for status, and often just to pass the endless hours of confinement. Trips to the infirmary are a frequent occurrence as inmates are viciously attacked and beaten, but the guards say they are powerless to end the abuse.
