In Season 3, Hard Time takes viewers on a yearlong journey behind bars, following the lives of those who work and serve time in two of Georgia's toughest maximum-security prisons. Episodes include Battle Behind Bars, World Without Men, Women on Lockdown, Gangs vs. God, Cellphone War, Prisoner Protest, The Convict Cycle and The Outsiders.

This documentary series focuses on extreme construction projects -- be they the biggest, tallest, longest or deepest in the world -- and the machines used to create extraordinary structures.

Lockdown plunges head-first into the gritty underworld of some of America's most fearsome prisons. Three thrilling hours provide an unprecedented immersion into life in the "big house": vicious gang leaders, a "prison pretty" newbie, and a gangster turned rat. In this world of absolutes, predators stalk their next prey, gang commanders order hits from isolation, and inmates are armed with deadly weapons. But the prisons are striking back. Institutional weapons of choice include state of the art surveillance and old school isolation. Officers are armed to the hilt with steel batons and pepper spray. Our cameras are there, in the middle of this real-life war zone, where only the strong - and the devious - survive.

Gives a picture of those creatures that hunt and are hunted by bites and stings.
