This high-budget production follows a German gynecologist who can't resist the temptations of her profession. She delights in exploring her patients' most intimate places, her eyes gleaming with lust as she probes their tight holes. But her most enticing patient is her own son, with whom she shares a secret, incestuous relationship. In explicit detail, the film captures their forbidden love, with the mother teaching her son the intricacies of lesbian sex, anal play, and the pleasures of rimming, all while speaking in multiple languages.
