The Embryo Hunts in Secret

Marukido (Hatsuo Yamaya) keeps his girlfriend Yuka (Miharu Shima) tied up inside his small apartment, where he undresses her, binds her, whips her and cuts her with a razor blade. Kōji Wakamatsu made it in July 1966, months after leaving Nikkatsu to start his own company, and it was his first film outside the studio system. Most of it passes between these two people, the man who gives the orders and the woman who is made to take them.
