Cleveland 'Stack' Stackhouse is a guard with the Texas Correctional Youth Authority who witnesses the cycle of destructive choices and racial tensions among female teen offenders and decides to do something about it. He gathers African-American, Latina and Caucasian teens, and organizes a multi-racial track team behind the bars of the prison. Participation in Stack's track team not only breaks down the racial divides between the girls, but puts them on a path to turn their lives around.
