Hong Kong's housing estates are poor and backward, and the adults in the housing estates are busy making a living and have no time to discipline their children. The children in the housing estates have nothing to do all day and form gangs. This has become a hotbed for the growth of gangs. Shan Ji (played by Jordan Chan) grew up in such an environment. He mixed with Bao Pi (played by Lam Siu-fung), Chao Pi (played by Chu Wing-tong), and Da Tian Er (played by Michael Tse) all day long. He gradually grew up and became a typical young and dangerous man made in Hong Kong. Shan Ji has liked the little girl Zhi Zhi (played by Gigi Leung) who is his childhood sweetheart next door since he was a child, but Zhi Zhi does not like to associate with young and dangerous men and gradually alienates Shan Ji. Shan Ji discovered by chance that Zhi Zhi came out as a dancer. It turned out that Zhi Zhi's mother was seriously ill and was eager to use money. Zhi Zhi had no choice but to come out as a dancer. Shan Ji helped Zhi Zhi. Zhi Zhi's mother thought Shan Ji was a good person and entrusted Zhi Zhi to Zhi Zhi before she died. Shan Ji decided to send Zhi Zhi back to Macau to settle down, but at this time, there were complications. Can the two finally get married?
