Officials and businessmen in Songjiang City colluded, and black and white were confused. Deputy Director Qiu of the Police Department was willing to act as a protective umbrella for the black-hearted businessman Chen Yiwen, and indulged the Jishengda Company he operated to engage in various short-selling, cheating and deceiving activities. To make matters worse, Chen Yiwen's (Hou Tianlai) younger brother Chen Yilong (Zhao Hengxuan) has a background in the underworld and actively acts as his brother's claws to clean up all those who dare to go against the brothers. Jackals, tigers and leopards cover the sky with one hand, making Songjiang City smoky. What is chilling is that Chen Yilong put on a police uniform under the arrangement of his brother, and he used all kinds of shameful means to rise straight up and became a gangster brother holding national power, with unlimited limelight. In contrast, Wei Tao (Ren Chengwei), a low-status police officer in the police station, is not afraid of violence and is upright. He has repeatedly tracked down the criminals, and it is inevitable that he will be hated by the thugs. And his fateful duel with Chen Yilong will eventually kick off... This film is adapted from real events.
