Su Ran discovered that her husband Jiang Lin used her salary card to support his mistress Zhao Wan, and even accidentally discovered that the account had abnormal water flow. Instead of being hysterical, she calmly collected evidence and called the police on suspicion of money laundering. After Jiang Lin was arrested, Zhao Wan rebelled to protect himself, and the driver Chen Chuang found out and handed over the account book. Su Ran personally sent her husband to prison, but had to face her mother's tears and the pressure of public opinion. A marriage funeral was also the prelude to her new life - when law and emotion clashed, she won dignity with reason.
