A showdown between a man who commits crimes in the name of "savior" and the Hong Kong police. The work focuses more on the confrontation between the weak and the weak, and the final self-redemption of people in a "sick" society. In the film, Cheng Yuanyuan plays the leading female role "Zhou Jieyi", and she and Tang Wenlong play Hu Mingzu, a couple. They are simple and pure characters with simple and delicate minds. They do their best with "family" as the axis. They are both good wives at home and spiritual pillars for their husbands.
