Predators Behind Bars

M1, T2: National Geographic takes you inside Ohio's Lebanon Correctional Institution as a new inmate is thrown into a mix of nearly 2,200 of the state's most dangerous and conniving criminals. Can a new inmate learn the ropes fast enough to survive his first month behind bars? And the leader of the Crips, one of Lebanon's most powerful gangs, is up against something even he's never dealt with in prison. National Geographic takes you inside this prison that the public doesn't get to see.
