【Synopsis】
An explosion suddenly occurred in a warehouse in the north of Binhai City, resulting in a citizen being injured. During the investigation, Xu Zhongmin, the head of the bomb disposal team of the special police team, found that the explosion residue at the scene was very similar to a jewelry robbery case eight years ago (called the "June 11" case). A batch of detonators from a quarry in the suburbs of the city were stolen and made into homemade bombs by the suspect Chai Zhifeng. During the robbery, the bomb carried by Chai Zhifeng suddenly exploded. This made Xu Zhongmin think that it was his dereliction of duty. He has been taking care of Chai Zhifeng's mother and his mentally retarded brother Chai Zhifei for many years. At the case analysis meeting of the Municipal Public Security Bureau, Director Gu Guangrong decided to handle this explosion case together with the "June 11" case eight years ago, and instructed Xu Zhongmin and members of the special police bomb disposal team to assist Qiu Jie of the criminal police team to set up a special task force to jointly solve the case.
In the early morning of this day, Ah Gui, who had just been released from prison, returned to Binhai City. Ah Gui came back to find Uncle Diao to get back a large sum of money owed to him for the jewelry robbery eight years ago. Uncle Diao promised to give him some money first, and arranged for Ah Gui to meet at an unmanned warehouse in the north of the city. Unexpectedly, an explosion occurred as soon as Ah Gui arrived at the warehouse. Ah Gui was injured and fled. Ah Gui believed that Uncle Diao wanted to kill him. Uncle Diao also thought that Ah Gui blew up the warehouse, so he sent his men to search for Ah Gui's whereabouts. From then on, the two sides began to compete one after another.
