Kimura wins a trip to Hong Kong, but once he arrives, he is mistaken as a hitman and is assigned to kill Yumiko, the female successor to the Ota Group conglomerate. When Kimura falls for his target instead, he must learn kung-fu from a local (Yuen) to fight off the yakuza assassin "Invincible" assigned to finish the job.
