In the economically developed eastern Guangdong Province, Luoyuan County is a county with the lowest public security. The sweeping era of anti-gangsterism and anti-evil swept it into the midst of it. Young criminal policeman Wu Jian encountered obstacles from evil forces while investigating a shooting case. The evidence returned to the police force disappeared. He could not clear his suspicion. Only Wen Luyang resolutely chose to believe Wu Jian and invited him to cooperate with the task force. Wen Luyang, who did not follow the routine, and Wu Jian, a straightforward young man with rough but delicate manners, formed a pair of different styles of solving cases. The two influenced each other in mutual testing. From the shooting case to the bald head murder case, they unraveled the largest underworld organization in Luoyuan County - the Chen Brothers Group. However, behind the case, there is a huge umbrella involving a larger force. How will they break through the local evil obstacles and return the people to a clear mind?
