Madame O on AllMovie

An esteemed Japanese doctor leads a violent double life in director Seiichi Fukuda's audacious pinky violence classic. Seiko (Michiko Aoyama) was just sixteen years old when three grown men ravaged her and left her for dead. Left pregnant and infected with syphilis in the wake of that violent attack, Seiko did her best to move beyond that fateful trauma by becoming a highly respected doctor. But no amount of career success can suppress the fury that has been building in Seiko over the years, and when night falls over the city she prowls the streets like a huntress in search of prey. It's all so easy too, because the men always seem to fall directly into her deadly trap. Seiko's weapon is sex, and she wields her weapon like a surgeon wields their scalpel. As long as there are men to be made suffer, Seiko will oblige. . . until she finally meets the man of her dreams, that is. Later, when Seiko settles down and gets married, her life finally starts to change for the better. Unfortunately for Seiko, her outwardly perfect new husband (Arihiko Kaminara) has a few dark secrets of his own.
