The series follows a group of rule-abiding students—Zack, Lawrence, Freddy, Summer and Tomika—who 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 and 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.
