At the onset of her sexual awakening, 19-year-old Danish teen Katja (Helli Louise) walks in on her father (Ole Wisborg) and new stepmother (Gio Petré) during sex. Hurt and hungry for revenge, Katja embarks on a lurid scheme to discredit her stepmom and reclaim her father’s attentions. Her outrageous and often lurid attempts push the soft-core envelope in this sexploitation melodrama from erotica auteur Joseph Sarno.
Joe Sarno is one of the pioneering directors of the 1960s sex-exploitation or “sexploitation” film genre. Known for a distinctly economic style and an abiding interest in tense, psycho-sexual character development, Sarno has also come to be recognized as one of the true geniuses to emerge from the sexploitation form. He continued to direct under various pseudonyms in the hardcore feature genre of the 1970s and ’80s, but is best remembered for such pre-pornographic classics as Sin in the Suburbs, Moonlighting Wives, The Bed and How to Make It and Inga. Along with Russ Meyer and Radley Metzger, Sarno is one of the few sex-exploitation auteurs to receive critical attention. In recent years, his work has been the subject of retrospectives at the New York Underground Film Festival, the Torino Film Festival in Turin, Italy and the Cinémathèque française in Paris. —IMDb
