Released from the detention center, the runaway young man Aaron (Zhang Tianxi), hesitating on the streets of Dragon Ball, saw his former young companions, who were no longer unemployed at home, and they set up individual stalls, including: hairstyle houses, roasted wax stalls, and also sold sausage powder, opening clothing stalls, which are really various. Some have become "10,000 yuan households" within a year.
Aaron was determined to be a real dragon. He sold all the TV sets, tape recorders, and watches at home, borrowed some money from a friend, bought an imported motorcycle, and invited his friend Hai Chai (Lai Chi Keung) and his girlfriend Zhu Zhu (Yang Liyi) to open a "Yamaha" fish stall named after the motorcycle brand "Yamaha".
Aaron only knows how to make money, and even does not hesitate to make money, which ruins the reputation of the fish stall. Three friends parted ways.
The clever ghost Hai Tsai goes on to cheat money again, and Zhu Zhu's mother (Wong Kam Tong) forces her daughter to go on a blind date with a Macau guest. Zhu Zhu's heart is in love with Aaron.
Aaron is going to be a real person. Just when he is depressed, Kui Mei (Xu Ruiping), the head of the Dragon Ball Street Individual Workers Association, extends a warm and friendly hand to him and invites him to participate in his fish stall. Kwai Bo (Shi Jian) and Kwai Mei's incomparable trust in Aaron inspires his enthusiasm for work. Aaron also learned the value of life from Aoi Mei's actions, which is not only career and money, but actual contribution to society! He retrieved the fallen sea boy and reconciled with Zhu Zhu, and they formed a new joint entity. They set sail for life and sail to the other side of the ideal.
