Empress Su Yunzhao disguises herself as a man and sneaks out of the palace to enjoy some music. At Qingyin House, she encounters Pei Jingxiao, heir to the Marquis of Dingbei, abusing his power to bully the performers. She bravely steps in to stop him, but her identity is accidentally exposed, and she ends up being detained by him instead. At the critical moment, the Emperor arrives and gets to the bottom of the entire case. The Marquis of Dingbei brings up his past achievements and desperately pleads for his son, but Su Yunzhao stands firm on the law and refuses to show favoritism. With the evidence against Pei Jingxiao conclusive, he receives the punishment he deserves under the law. Once the turmoil settles, Qingyin House is renovated and reopens. Su Yunzhao and the Emperor finally change into ordinary clothes and sit peacefully inside, enjoying the graceful music and dance.
