Maryland inmates give a group of five at-risk teens a taste of prison when they are forced to eat "Lock-up Loaf," a brick of baked mush served to unruly prisoners. The teens include, Shane, 17, a redneck who is surprised he hasn't killed anyone, Garrett, 13, who HAS been kicked out of eight schools already, Brandy, 16, who skips school to smoke pot, her brother Shawn, 15, who protects Brandy at any cost and Richard, 18, a towering jock who drinks, blacks out and awakens bloodied from brawling.
