The main plot follows struggling rock singer and guitarist, Dewey Finn (Jack Black), who is kicked out of his band and subsequently disguises himself as a substitute teacher at a prestigious prep school. After witnessing the musical talent in his students, Dewey forms a band of fourth-graders to attempt to win the upcoming Battle of the Bands and pay off his rent. The picture's supporting cast features Joan Cusack, Sarah Silverman, and Mike White. A stage musical adaptation is planned to open on Broadway in late 2015, with a television adaptation for Nickelodeon also planned.
