The film is set in the Kowloon Walled City, a place where three dragons and snakes are mixed, and was once known as the paradise of yellow gambling and poison. Here, as long as there is strength and power, it is natural to run amok, although the local environment and living conditions are poor, but it is easy to become a hotbed of evil. Photographer Greg Girard has entered the Kowloon Walled City many times to shoot, and compiled the photos into a photo album "City of Darkness", which can be imagined by looking at the name. The city has 154 drug colonies, 11 pornography venues, 7 casinos, and 13 dog meat shops, as well as numerous dentist clinics and food processing plants, most of which operate illegally or without a license. Today's Kowloon City Walled City has been demolished, the traces of history have gradually changed, or many years later, there will be no more film and television works with this theme background.
Film works involving walled cities, more or less in the shooting method, are a bit more biographical and reminiscent, and this one is no exception. The first half of the story is told too slowly, the time span before and after is also large, and the days with unlimited scenery in the back seem to be deliberately skipped, as if its main theme is serving the love of the four protagonists, but this love is shattered. Liu Qingyun, as a black man, used everyone, and only in the end did he realize that he should not have been in the beginning, but unfortunately there was no if, this is life.
The young Liu Qingyun and Wu Zhenyu followed their uncle into the Kowloon City Walled City to open their eyes, only to be attracted by all kinds of people and things, so they mixed here and got to know Zhu Yin and Peng Dan. After seeing through the way the walled city exists, Wu Zhenyu is determined to become a policeman, while Liu Qingyun, who has a brain and arrogance, is mixed with the underworld. Originally, the two brothers took good care of each other, but as a result, Liu Qingyun ghostly hooked up with Zhu Yin and failed Peng Dan and his good brother Wu Zhenyu, who had always been in love, but this sneaky thing, everyone knew it, but no one said it.
After Wu Zhenyu gradually rose and his temperament began to change, Liu Qingyun was determined to help him ascend to the position of inspector for his own position, and the two brothers began to cover the sky with one hand. But Wu Zhenyu is too high-profile and too out of position, and his heart is fierce and unscrupulous, and the differences between the two brothers have gradually arisen. In addition, the person who was replaced by Wu Zhenyu naturally did not give up, and sent Xie Tianhua to investigate undercover, and as a result, Xie Tianhua and Zhu Yin got involved again, but if Zhu Yin's wrist was stronger, she would become wu Zetian of the walled city.
Xie Tianhua betrayed Wu Zhenyu again, and also killed Zhu Yin by mistake, plus Liu Qingyun and Zhu Yin's old past, new hatred and old hatred, Wu Zhenyu broke out. However, his venting is reasonable and quite unexpected, and he eventually died under the police shooting. Liu Qingyun, who was shot in the body, was lucky not to die, but it was difficult to regain the glory of the past with a lame foot.
