chunk: Mick O'Brien (Sean Penn) is a 16-year-old Irish-American hoodlum from Chicago. While most of Mick's crimes involve snatching purses, vandalism, and getting into brawls, he aspires to bigger and meaner things, which leads him to attempt ripping off a Puerto Rican rival, Paco Moreno (Esai Morales). Everything goes wrong: Mick's partner and best friend Carl (Alan Ruck) is killed, and Mick, while trying to escape the police, accidentally runs over and kills an eight-year-old boy who happens to be Paco's brother. Mick is sent to the Rainford Juvenile Correctional Facility rather than a state prison for adults. Most of the wardens and counselors seem to have lowered themselves to the role of zookeepers. The only exception is Ramon Herrera (Reni Santoni), a former gang member who talks tough to the inmates, but holds out hope for some of them, especially Mick.
