| 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. |
