But when an anti-music group, the Aletheia, send Jack to steal the rock star's guitar, Emerald's true calling is discovered. If she doesn't accept the unwanted gift she's been given, and leave her comfort zone, music and everything on which it depends will disappear. All life. All people. All existence. The entire universe as we know it...'
