Fatal extramarital affair

Jin Wan (Yu Jinbao ) is a wealthy business tycoon. Because his wife Xiao Min was too weak to have sex with him since childhood, he vented his desire on his mistress. However, Jin Wan's two mistresses were killed one after another, and it was a mysterious man in black who killed them. In order to solve the case, policewoman Zhou Ling (played by Lin Yuzi) disguised herself and began to approach Jin Wan. Little did she know that Xiao Min's younger brother Guowei really mistakenly thought Zhou Ling was his brother-in-law's new mistress. The angry Guowei wanted to teach Zhou Ling a lesson, but was arrested for this. Just when Jin Wan was about to redeem Guowei, he was attacked by a man in black, and Guowei was cleared of the suspicion of the murderer. Later, Guowei's girlfriend Meihui was also injured by the man in black and was admitted to the hospital.
