comedy teacher uses props to teach kids about washington crossing the delaware river

Fired from his band and hard up for cash, guitarist and vocalist Dewey Finn finagles his way into a job as a fifth-grade substitute teacher at a private school, where he secretly begins teaching his students the finer points of rock 'n' roll. The school's hard-nosed principal is rightly suspicious of Finn's activities. But Finn's roommate remains in the dark about what he's doing.

A group of rule-abiding prep school students – Zack, Lawrence, Freddy, Summer and Tomika – learn to take risks and reach new heights thanks to substitute teacher Dewey Finn, a down-on-his-luck musician who uses the language of rock ‘n’ roll to inspire his class to form a secret band. Throughout the school year, these middle-school classmates find themselves navigating relationships, discovering their unknown talents and learning lessons on loyalty and friendships.
