In Shanghai in 1930, Gu Niansheng, the leading lady of the Tianchan stage, was mistaken for the eldest lady who had been missing for three years at a warlord hall. The moment she stepped into the wealthy family, she touched the tea cup and saw the murderer's face. Poisoned tea, substitutes, arms smuggling, human trafficking - she relies on her "criminal judgment" ability to survive every step of the way amid numerous murderous opportunities. On the stage, she is a famous actress who captivates everyone; in the mansion, she is a hunter with no tricks left. Everyone thought she was a chess piece at the mercy of others, but they didn't know that she had already seen through everyone's next move. This play is not finished yet.
