This Rainer Werner Fassbinder drama centers around the lonely quest for love of Elvira Weishaupt, a man who became a woman to please his/her man. Just prior to that, Elivira had been jilted by her previous live-in partner, a man. She does the operation to win the heart of another, Anton.
Unfortunately, the sex-change operation does not change the intended's mind; Anton is simply not interested.
