Li Dayou (Felix Wong) and Li Qi (Eric Tsang) are father and son. They are the heads of several gangs and they are working together to set up a debt collection company. Dayou is known for his brutal methods and is feared by debtors. Zheng Jifeng (Yin Yangming) blamed himself for the tragic death of his wife in a traffic accident while trying to save his four sons. However, he has not been liked by his father Zheng Sen since he was a child. After graduating from elementary school, he was arranged by his father to work as a stable groom. Qian Qian (Sammi Chan) and Zhong Ailing (Ada Choi) jointly opened a small company. Due to failed investments, they were heavily in debt. Under the constant intimidation of Youyou's debt collection company, the two were almost desperate. Qian and Ling entered the race on the horse racing day to try their luck, but unfortunately they lost all their money. When Ling thought that she was at the end of her rope, she saw Qian taking out a large sum of money to bet again. She then realized that she had been hiding something. Jifeng believed what his brother Jilong said and lost all the money on him. She then realized that Long was teasing him. After getting along with Shallow, Ling and You, they found that he was not as cruel as they imagined, and they even cooperated to develop the karaoke business. You found that the horse racing business would definitely make a fortune, so he cooperated with the underworld boss and made a lot of money. You decided to participate in the event yourself and become the owner of the horse, and visited the poor horse trainer Lin Deng (Li Jiading), but when You invited Feng to participate, it aroused his disgust. After getting along with You, Shallow unconsciously used his true feelings for him, and Ling also admired You. At the same time, You also had a good impression of Shallow. The horse "Dream King" purchased by You was tough and difficult to tame. Fortunately, the horse master Yiming trained patiently and finally ran a good result. On the other hand, the tycoon Paul admired Feng very much. Feng felt the grace of meeting Paul, so she worked hard for Paul. Xiaolan visited the racecourse and met Feng. Lan finally fell in love with Feng, but Feng did not dare to appreciate it because of her humbleness. You and Qian's relationship gradually stabilizes, and they are planning to get married. On the eve of their wedding, You discovers Qian has embezzled public funds. Qian thinks that the marriage is off and absconds with the money. At this time, Da's business encounters a crisis and he declares bankruptcy. Afterwards, he suddenly feels that he has failed Ling's love, and marries Ling. You is ready to regroup and challenge Guan He, while ignoring Ai Ling. Finally, You wins a great victory and is about to marry Ling, but he cannot forget Qian in his heart. You gathers funds from various wealthy people and prepares to build a racecourse in the mainland, but because the government criticizes the gambling of horse racing, You and Feng both die.
