Stranded and stripped of his abilities, JSonic must team up with a band of unlikely heroes—mysterious locals who secretly yearn for sounds of freedom. Together, they set out on a daring mission to restore the beat, sparking a movement that will resonate across the cosmos and bring harmony back to a universe out of tune.
