Night and Fog in Tin Shui Wai is based on the sensational massacre in Tin Shui Wai. In the film, Yam Tat-wah plays a Hong Kong native, and Zhang Jingchu plays a woman who comes to Hong Kong from the mainland. The story takes place between two people who grew up in different environments, and Yam Tat-wah finally kills his wife and two children and then commits suicide. Although the news reports at that time portrayed the hero as an evil character, Xu Anhua's lens gave the murderer enough motive to kill and a tragic fate.
