In the mid-'80s, when the rising hardcore video market was hurting Nikkatsu's business, they launched a series of "nostalgic" S&M remakes starting with Hana to Hebi: Jigoku-hen. Masaru Konuma, popular director of the landmark Ikenie Fujin, began the Nikkatsu studio's series of S&M films with this well-done tale of an investment banker named Yoshi (Yasuhiko Ishizu) who is scarred by a childhood trauma. As a boy, Yoshi kills a black American soldier for consorting with his mother. He grows up impotent unless he is able to bind and whip his sexual partners. No one at his company knows, until the president (Nagatoshi Sakamoto) asks Yoshi to give his frigid wife (sex film queen Naomi Tani) an education. Needless to say, the education Yoshi provides is hardly what his boss or his new student had in mind. Hiroko Fuji co-stars.
