Directed by Wu Tiange, Nuandong (Warm Winter) centers around Gou Qiang (Wang Xuebing), a workaholic detective who lives by himself in an apartment littered with enlarged photographs of his current suspects. At the heart of his projects is Lu Hanqing (Wang Ji), a woman put under surveillance in the hopes that her former lover (and professional con-artist) would return. While her middle-aged ex does, indeed, come back, an unforeseen attack leads him back into obscurity. Lu, now aware that she is being followed, initially thinks Gou is a stalker, and threatens to alert the police. Once she realizes he is the police, a mutual attraction between the two slowly develops. ~ Tracie Cooper, All Movie Guide
