On Li Guihua's fiftieth birthday, an old dog carrying a bloody red padded jacket breaks in, exposing that the visiting daughter is a fake. Relying on dietary taboos, past events, and a red mole, she confirms her biological daughter Qiaoyun has been imprisoned by the Cui family for three years, who intend to scam them out of their land deed and force a severance agreement. Guihua takes her son to Jinling, disguises herself to sneak into the Cui residence as a maid, unites fellow victims and the newly arrived Censor, and publicly exposes the Cui family's crimes of imprisoning wives, bribing officials, and identity substitution. In the end, the villains face justice, and Qiaoyun returns home safely. The family guards their reunion, using actions to prove that her maiden family is always a daughter's strongest backing.
