Làng Wū Yáo is a boy born with a supernatural singing voice. Secluded in the snowy mountains, he is put through severe training by his blind mother. Her wish is for her son's voice to be unrivaled, so that it will be heard by the imperial court. But the intense training results in a tragic accident, where she dies. Left an orphan as a result, Làng wanders the land. His voice is used as a tool by the wicked and greedy, with his heart being ground down in the process. Eventually his strange singing catches the ear of the princess of Xī Yōu, and Làng is elevated to the stage his mother had dreamt of. But what awaits him is a life or death battle performance against other musicians for the amusement of the members of the court.
