Ah Huo (Jackie Chan), a garage mechanic, has a hot temper. He is not only agile, but also has first-class driving skills. It is only because of his poor family that he has never realized his dream of becoming a racing driver. One day, the police found him and hoped that he could help arrest Cook, the leader of the car theft group. Because Cook has first-class driving skills, the police set up roadblocks and chased him many times but got nothing. Ah Huo readily agreed. With the help of Ah Huo, the police finally caught Cook with great effort. However, Cook was rescued by the gang's accomplices during his detention. The car theft group also attacked Ah Huo's garage. Ah Huo escaped by luck, but his two sisters were seriously injured. Cook then joined a Japanese racing team and asked Ah Huo to compete on the Japanese track. In order to get revenge, Ah Huo resolutely participated in the competition!
