Su Wantang, the concubine of the Hou Mansion, was sent to a theater troupe by her mother-in-law Shen to work as an acrobat because of her mother's early death. When she was fifteen, she was recalled to the Hou Mansion as a maid for the purpose of humiliation. She used the observation, acting and acrobatic skills she learned in the theater troupe to pretend to be weak and secretly investigate the cause of her mother's death, and to deal with the difficulties caused by Mr. Shen and his concubine. During this period, he met Gu Zhaozhi, the legitimate son who appeared to be a playboy but was actually a strategist. The two went from testing to fighting side by side. While using her acting skills to resolve the family crisis, Su Wantang returned to the troupe to perform and became a famous actor in the capital. Eventually, she exposed Shen's conspiracy, regained her identity as a legitimate daughter, became the ruler of the family and the leader of the troupe, and gained both love and career.
