The Switch | 1973
Dr. Shirley Jekyll is a research scientist who lives with her sister Louise and her oversexed husband. Shirley is in love with her colleague Dr. Bill Jenkins, but is too shy to tell him. Since she is working on a new serum that causes changes in physicality and behavior of its subjects, she decides to test it on herself. The chemical transforms her into Sherry Hyde, a woman with a voracious sexual appetite, who is not only beautiful, but so sensuous that she emits a scent that is irresistible to both men and women. Now she easily seduces Dr. Jenkins, but not satisfied with her dream man, she indulges in sex with everyone in sight.
