Li Shaohua, a habitual thief, died mysteriously at home. Wu Feng, the captain of the criminal police, was responsible for investigating the case. As the case progressed, the target was pointed at Zhu Zi, the general manager of Shengtian Company. Shengtian and Wu Feng were good brothers who grew up together, and the two families had a very good relationship. He made a fortune by doing jewelry business. Wu Feng found out that the jewelry products of Shengtian Company were of unknown origin, and the police's suspicions were confirmed one by one. Zhu Zi was the mastermind behind the scenes. At this time, a bigger economic case quietly occurred, and a large money laundering gang had entered the city. The police found that Zhu Zi had close contact with the gang. In order to play a long game, the police temporarily shelved the arrest of Zhu Zi. After careful investigation, it was found that the real mastermind behind the scenes was actually Shengtian and his wife. Because of his relationship with Shengtian, Wu Feng requested to avoid it. The leader approved Wu Feng to continue investigating the case. Shengtian realized that the police had suspected him, and ordered Zhu Zi to steal jewelry crazily to divert the police's attention so as to buy time for his money laundering plan. The law is long and there is no loophole, and evil can never defeat justice. Faced with his crimes, Shengtian finally chose to end his life.
