In this hour, a production team reveals what it's like to be up-close and personal in a maximum security lockout.

WTF. It's not what you think it means. It stands for workouts... tattoos... and food.

A U.S. marine violates the code and now faces a murder charge. A would-be soccer mom takes up with a violent street gang. An openly gay inmate adheres to the convict code and pays the price. And a young inmate goes home to the father who had him arrested.

Inside prison or jail, regrets are never in short supply. And as if watching Lockup isn't warning enough for some... prisons and jails use inmates to warn troubled teens before it's too late. And others express their regrets with personal cameras that we call "inmate cams."

For some, jail is the ultimate limbo between freedom and a life behind bars or even worse. And for better or worse, time in jail changes everyone.

Some inmates discover beauty in lines, while others cross them.
