Chan Foh To is a junkyard mechanic and a part-time race car driver who helps the Hong Kong Police Force in their crackdown on illegal street racing in the country. One night, while helping news reporter Amy Yip and Mr. Lam after their Mitsubishi FTO runs out of gasoline, Chan commandeers the car with Amy inside to chase after a speeding black Nissan Skyline GT-R#Third generation (1989–1994) driven by the dangerous criminal driver Warner "Cougar" Kaugman. In the high speed car chase's climax, Chan traps Cougar in a police roadblock and has him apprehended. However, due to a lack of evidence and a warrant for arrest, Cougar is immediately released from police custody. Chan continues to be harassed by Amy, who wants to do a cover story of him.
