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.

Koyuki Tanaka was feeling the rut, though he’s only a teenager. Between the sheltered and stifling grind of school and the girls that spend their time not noticing him… Every day was just another day of being a total nobody. Enter Ryusuke: a local rock n’ roller haunted by a shady reputation. Together they form Beck, a dynamic band that just might be the salvation of the stagnant music scene. Sure, it’s going to take hard work and obsession to make it, but there’s something special in the sound. If the guys can stay true to their vision, the world awaits. Music can change your life, sometimes against your will. Just remember… When it’s live, anything can happen.
