During a trip, Zhang Huifang meets Zhao Zhiyuan, who is articulate and graceful. He is gentle and considerate, constantly portraying a guaranteed-profit investment blueprint, and Zhang Huifang gradually falls deeply into it. Her daughter, Zhao Keyi, investigates through various channels and discovers that Zhao Zhiyuan is a habitual fraudster. She kindly discourages her mother, but instead gets misunderstood by her and kicked out of the house. Zhang Huifang and her son Zhao Kewei continue to invest, emptying their savings, roping in sisters to join the scheme, selling their house, and borrowing high-interest loans. Zhao Zhiyuan suddenly disappears, and creditors come to demand payment, leaving the mother and son desperate and seeking help from Zhao Keyi. Zhao Keyi calls the police to recover the remaining funds and redeem the property. Zhang Huifang wakes up abruptly and devotes herself to anti-fraud publicity, while Zhao Kewei also settles down to work, abandoning the illusion of getting rich quick.
