Shen Qingqiu, a famous Kunqu opera singer and the pearl of the opera garden, aspires to win the "Plum Blossom" title. Jiang Mohen, the personal servant, is as silent as a shadow, but possesses a lost art. Master-servant contract: She uses his secret help to reach the top, and he uses her to rekindle the stage.
