Niizuma kahanshin: Washizukami(1991)

Overview

This deliriously warped S&M softcore film from cult pinku-eiga director Hisayasu Sato deals with a deranged doctor who lives in an abandoned hospital with his wheelchair-bound daughter. Frustrated by normal women's perceived imperfections, the doctor kidnaps them and subjects them to sadistic tortures to turn them into subservient women for his childlike daughter to play with.
