It's been years since rocker girl Sona Song last talked to her father, a famous classical music conductor. So she's shocked, and a bit annoyed, when he leaves his orchestra to her after he dies. Though Sona just wants to slack off, she's soon visited by Yin Le Hao, her father's musical protégé from China. Hao doesn't speak any English, but he's determined to whip the orchestra into shape no matter what.
