Jace and the SlipDog members are unable to write any good songs. Meanwhile, Jace's father Eric is depressed because he did not succeed at music but manages an amplifier and guitar repair store. When Jace hears one of Eric's unfinished songs on an old audiocassette, he is finally inspired. At a concert attended by Jace's mother Gina, Jace invites Eric to come onstage and perform a piece with the band—the song from the tape.
