A showdown between a man who commits crimes in the name of "savior" and the Hong Kong police. The work pays more attention to the confrontation between the weak and the weak, and the final self-atonement of people in a "sick" society. In the film, the female lead "Zhou Jieyi" played by Cheng Yuanyuan and Hu Mingzu played by Tang Wenlong are a couple. They are a simple and pure character with a simple and delicate mind. They do their best with "family" as the axis. She is not only a good wife in the family, but also the spiritual support of her husband.
