Tabitha.  Shelby.  Lisa.  They're longtime friends on separate life paths, but they share a horrific destination when a seemingly innocent incident from their school days comes back to terrify them.  Something-someone-wants payback; warped vengeance....mind-games vengeance...taunting, shredding, slashing vengeance.  Inside a stone-walled chamber of prison cells and mechanisms of doom, the three women and other victims face a fierce fight to survive.  Who lives?  Who Dies?  It's all for someone's Amusement.
