LouAnne Johnson is a Marine turned teacher who squares off against a classroom of impudent, inner-city teens, whose bullying tactics nearly drive her out the first day. But Johnson radically changes her lesson plan to include bribery and browbeating (despite objections from the school's prissy principal) in an effort to teach the class that learning is its own reward. Based on LouAnne Johnson's autobiography "My Posse Don't Do Homework".
