Zhang Baolin, the prototype of the TV series "Conquest" in Liu Huaqiang, was the boss of a certain underworld in Shijiazhuang. He was arrested and shot according to law in Shijiazhuang, which triggered a vicious struggle between the black forces and led to a murder case.

Introduction to the conquest story:

On the evening of April 28th, 20001year, an armed robbery happened in Fan's alley near the downtown area of Hengzhou City. Xu Guoqing (Zhaoqi Shi), deputy director of the Municipal Public Security Bureau in charge of criminal investigation, rushed to the scene immediately after receiving the report. During the investigation, the police found that the victim Wu Tian's background was extremely complicated and he had deep grievances with many people. After analyzing the case, Xu Guoqing had a premonition that it was a vendetta involving a black gang feud.

The police launched a full-scale pursuit and arrested a group of members of black gangs who ran rampant in Hengzhou, but none of them were behind the "4 28" gun case. At the same time, Liu Huaqiang (Sun), the maker of the "4 28" gun case, is stepping up planning and implementing his evil plan. Li Li (Jison), the boss of a real estate company in Hengzhou City, is very frightened when he hears the news that Wu Tian was killed. He asked Liu Huaqiang to meet him.

For the safety of her sister Li Mei (Liu Weiwei), Li Li offered to take Li Mei away, but Li Mei refused. Just when the police investigation was at a loss, Liu Huaqiang took an evil look at the next target. The pursuit and anti-pursuit between the police and robbers, and the contest between revenge and revenge prevention began.
