Ran (Shimamura) comes to Japan, and makes an immediate impression by assassinating a Yakuza boss and his associates, while they dine in a restaurant. Escaping the scene, she hides out in the restaurant owned by Yoichi (Yamato), and thanks him for covering for her with her body. About three hours later – or maybe it just seems that way – she moves on with the rest of her mission, which is to extract revenge on those responsible for the death of her sister. To this end, she works at the same hostess club as her late sibling, and waits for opportunity to present itself. However, the remaining target (Hakruyu), aware of his peril, kidnaps Ran’s friend Chun Li, and uses her to lure Ran out of the darkness.
