Hardened criminals at the California prison that is home to Charles Manson give teens a taste of life on the yard, where any prisoner can approach the kids and give them a feel for the dangers of prison life. The teens include Stephen, 16, a violent youth who threatens his teachers; Josh and Armando, 16, twin brothers and gang members; Elijha, 15, a car thief; and Abraham, 16, who thinks that going to jail is no big deal.
