Jackie Chan dons a helmet and jumpsuit to stars in this critically panned action flick about crime and hotrods. Jackie is an ace car mechanic and an even better driver who gets himself involved with notorious bandit racer Cougar (Thoresten Nickel) during a casual street race. The Hong Kong cops have long been looking for Cougar for not only illegally modifying racing vehicles, but also for a string of less obscure crimes like murder and extortion. When Jackie beats the guy in the race, Cougar is furious. As a result of the race, Cougar gets dragged to the clink and vows revenge. Soon after, Cougar busts out of prison kills Jackie's parents, kidnaps his sister (Anita Yuen Wing-yee), and demands that he race him in the Sendai Grand Prix in northern Japan. Wild high-speed chases and a rollicking kung-fu fight in a pachinko parlor ensue.
