In the dead of winter, gunman Xiao Gu (Xia Yu) tracks down the killer Lao Jiao (Jin Shijie) who is lurking in the tailor shop. The two try to confront each other, and a tragic case that has been hidden for many years gradually surfaces in the confrontation between the two. The story background of the film is locked in Bincheng, Northeast China, after the surrender of the Japanese army in 1945. During this period, Bincheng fell into a vacuum period without management, and the underworld forces were rampant. Many characters such as Kui Shu (Li Liqun), Li Huan (Zhang Guozhu), Lao Gou (Gao Jie), Zhong Zhen (Tan Kai), and Lao Gui (Yang Haoyu) made their debut. In the old era of darkness and material desire, an epic legendary story about sticking to promises and sacrificing oneself for the sake of others has begun.
