Junpei, a low-level yakuza of the Soryu Group in Okinawa, steals 500 million yen from his boss Shinjo en route to a heroin deal.
Before Shinjo can punish him, the police raid the gang's office, saving Junpei's life by landing him in prison for five years.
Upon release, he offers 5 million yen to the invincible professional bodyguard Kiba of the Kaito Karate dojo to escort him to the hidden loot so that he can find his girlfriend Yoko, a Taiwanese prostitute, and escape forever.
The three men sneak into the club and rescue Maki, who helps them fight the other members of the Soryu Group at Shinjo's hideout.
In the nicely choreographed fight scenes, the former boxer Yamato Takeshi, can fully show off his skills as Bodyguard Kiba."
