Nami (Meiko Kaji) is back, and this time the Ginza Butterfly is on a mission to kill the man who murdered her father when she was just a young girl. Hoshiden robbed Nami of the only father she ever knew, and for that crime he must die. Upon arriving in Tokyo, Nami lands a job as a hostess in a swinging Ginza club. But when Nami's not charming customers, she's searching the local streets and gambling dens in search of her treacherous target. Enlisting the aid of local hustler Ryuji (Sonny Chiba) in tracking Hoshiden down, Nami soon discovers that he's adopted a new name, and he's currently hiding out in the yakuza headquarters. Storming the headquarters with Ryuji by her side, Nami stirs up a furious storm of steel and blood, and prepares to take violent revenge.
