Public high school is a private hell for the teachers and weaker students at Donner High. A beautiful, young teacher is molested at gunpoint. Other students are beaten and intimidated. Finally, a new substitute, Mr. Walmsley, a former Medal of Honor winner and animal trainer, decides to teach the bullies a lesson they'll never forget. A shocking substitute to the three-ring circus of the classroom, Walmsley's savage "reform school" becomes a house of horrors where students only survive... if they learn.
