The story revolves around pious, young Pierre who has just left a Catholic boarding schoolto live with his wealthy parents at their villa on the island of Gran Canaria. Pierre's father dies early in the movie, leaving his mother, Hélène to care for him. Pierre soon learns, however, of the depraved nature of his parents. While in a restaurant, his mother reveals to him that she has been unfaithful to her husband many times with his knowledge and feels no shame about it. She then insists that her son accept her promiscuous ways. Soon after this, Pierre finds a closet full of his father's pornography. His reaction is to furiously masturbate and then to urinate on the magazine pages. However, there are several far more shocking surprises in store for Pierre. Hélène encourages her uninhibited sex buddy, Réa, to take her son's virginity. She does so but in public and on a concrete floor at Gran Canaria's Yumbo Centrum, a popular shopping and nightlife complex. Hélène looks on longingly as the partially clothed couple copulates with passersby raising no objections. Afterwards, Hélène includes her son in an orgy with her friends, including Hansi, a sweet-faced young woman who later becomes Pierre's girlfriend. After the orgy, Hélène decides that she must leave her son to travel. While saying goodbye to Pierre, she implies that something taboo has happened between them and that she must leave to prevent it from happening again. Upon Hélène's departure, Hansi enters Pierre's life as a friend. She admits befriending Pierre at Hélène's encouragement but denies receiving a fee from her. Their friendship blossoms into a tender romance and they both fall in love. During their relationship, Hansi reveals that she has participated in sado-masochistic sex many times as a dominatrix with her friend Loulou as the willing masochist. She adds Hélène arranged these encounters as sexual exhibitions for tourists. After an extended absence from the movie, Hélène returns home with Réa in tow because Hélène has finally tired of her sexual adventures. Upon arriving, she finds her son and Hansi socializing at a bar near the villa. Hélène and Pierre greet each other by chatting and gazing into each other's eyes like lovers while Hansi looks on jealously. Finally, Hélène invites her son to sleep with her. He agrees. Hélène and Pierre enter the house's wine cellar. They begin to act out their desires physically. Hélène asks her son to cut her abdomen with a razor while he masturbates and as he climaxes she slits her own throat. In the next scene, paramedics take away Hélène's body. Pierre says good-bye to his mother before the cremation. He enters the room where she lies in state and masturbates exclaiming that he does not want to die as he is carried out.
Ma Mère was rated NC-17 when it was released in the United States. The reason was "strong and aberrant sexual content". For the trailer the film was presented as an NC-17 film while mistakenly defining the rating as "under 17 requires supervision by parent or guardian". An edited R-rated version running ten minutes shorter was released on DVD. The reason for the R rated version was "Strong Aberrant Sexuality, Some Language and Violent Images". Despite YouTube's policy of not carrying NC-17 rated films, YouTube simply falsely labeled the NC-17 version as unrated in order to carry it.
