Rock got no reason, rock got no rhyme… You better get me to school on time! School of Rock follows Dewey Finn, a failed, wannabe rock star who decides to earn an extra bit of cash by posing as a substitute teacher at a prestigious prep school. There, he turns a class of straight–A pupils into a guitar-shredding, bass-slapping, mind-blowing rock band. But can he get them to the Battle of the Bands without their parents and the school’s headmistress finding out?
