Su Wanzhao, the leading singer in the troupe, had her house confiscated by the Jin Yiwei and was sent to the palace to be used as a "princess stand-in" because she looked exactly like the late Princess Zhaoning. Relying on her acting skills and ability to observe people's emotions, which she has honed over many years of singing, she has successively solved the conspiracies of the imperial concubine's "poisoning", the empress's "false pregnancy", and the queen mother's "conspiracy in the Buddhist hall". She used "acting" to expose the enemy's hypocritical mask, and was promoted from the lowest palace maid to the master of the Sixth Palace. In the process, she and the forbearing prince's companion Xie Zhiyuan went from "mutual use" to "genuine love". The two teamed up to uncover the truth about the death of Princess Zhaoning and overthrew the Xiao family who controlled the government. In the end, Su Wanzhao became the queen and Xie Zhiyuan ascended the throne as the emperor, and worked together to protect the country.
