In going behind bars of Georgia's correctional system, each episode of this series examines one aspect of the state's paramilitary approach to their prisoners, the idea being treat them like highly disciplined soldiers and they will stop acting like criminals.

CNN is by and large still a cable news outlet, but a movement under the leadership of network president Jeff Zucker to provide more alternative, entertainment-based programming is clearly afoot, and "Death Row Stories" is a prime example. The eight-part documentary -- the result of a collaboration with Academy Award-winning directors Robert Redford ("Ordinary People") and Alex Gibney ("Taxi to the Dark Side") -- revisits compelling capital murder cases in the U.S., detailing the twists and turns involved in each as a thought-provoking exercise on the death penalty and the American justice system. "Dead Man Walking" Oscar winner Susan Sarandon is the narrator. Redford's Sundance Productions also partnered with CNN for the documentary series "Chicagoland."

"Lockdown" plunges viewers headfirst into life in the "big house," the gritty underworld of America's maximum-security prisons, where gangs are prevalent, predators stalk their next prey and inmates are armed with deadly weapons.

Told from the perspectives of both the escapees and the law enforcement teams tracking them, this series documents some of recent history's high-profile jailbreaks and the various methods officials use to outsmart the criminals, leading to their eventual recapture.
