Drug Dealing. Gang Beatings. Prostitution. They're all part of a typical day for the students of Lincoln High. Into this academic abyss arrives Andy Norris, an idealistic and naive music teacher who has moved into the community with his pregnant wife Diane. Appalled by the crime-infested school, Norris soon crosses sabers with its teenage kingpin, the shrewd and sadistic Peter Stegman. With Norris setting his sights on reforming Stegman, and the young miscreant declaring war on his teacher, the duo sets a fateful showdown into motion on the night of an important school orchestra performance.
