Set against the 1931 Madrid moment—the dawn of the Second Spanish Republic—a wealthy woman, Aurora Rodríguez, shapes her daughter’s life with unwavering control. After a union with a clergyman, she conceives Hildegart Rodríguez and then homeschools and mentors her, crafting a prodigy who she believes can, through intellect and action, change the world. The home they share is refined and protected, with a devoted maid nearby, while Hildegart’s talents quickly bloom into writing, public speaking, and a keen awareness of social issues that buoy her ambitions.
As Hildegart grows, her work and voice draw the attention of the era’s political currents. She becomes connected with influential figures and ideas, including a Socialist activist named Abel Vilella, who recognizes her gifts and potential. Hildegart’s letters and collaborations widen her circle, and she carries herself with a confidence that invites both admiration and scrutiny. With her mother’s guidance and her own charisma, she dives into political life, delivering a passionate speech at a socialist gathering advocating women’s rights and political participation, and she even participates in book-signing events that extend her influence beyond the page. Her burgeoning fame brings her into contact with Havelock Ellis, whose interest in her work and views fuels a growing sense of possibility about her place in the world.
But the relationship between mother and daughter becomes increasingly tense as Hildegart’s independence edges beyond the boundaries Aurora has set. The maternal maneuvering grows more intricate as Abel becomes a focal point for Hildegart’s affections, a tension Aurora perceives with discomfort and alarm. A later encounter—when Hildegart confesses her feelings to Macarena, whose loyalties shift as secrets multiply—pushes Aurora to tighten her grip, hearing and seeing everything from behind closed doors. The atmosphere of trust fragments as the two young people begin to chart a path that seems to stray from the strict plan Aurora laid out for them, and the mother’s determination to keep Hildegart within her control intensifies.
A curious twist arrives when Aurora receives a letter inviting her to a piano concert staged by Pepe Arriola, her nephew and another prodigy, who has also been under her wing. The backstage meeting reveals that the invitation was a ruse designed to give Hildegart a chance to spend time with Abel away from maternal surveillance. The moment raises the stakes: Abel is invited into Aurora’s social circle, where conversations about political shifts and youth movements reveal a shift away from the Socialist ranks toward alternative currents—currents Aurora views with skepticism and concern.
The tension peaks when police officers arrest Abel on charges framed as serial rape and feminicide, a shocking reversal that unsettles Hildegart and shakes her faith in the world she has begun to inhabit. Macarena disappears from the household, replaced by another maid, and Hildegart is forced to confront the possibility that those around her are not who they seemed. In a bid to clear Abel’s name, Hildegart seeks leverage, visiting Macarena’s humble home and pressing her to act, threatening to expose her as an accomplice if she does not intervene. With help from Guzmán, they arrange travel to London and urge Abel to accompany Hildegart on the journey—an escape that would fuse their futures in a new, freer life.
A final family dinner becomes the turning point. Hildegart declares her independence, telling her mother that she is now a woman free from anyone’s control, bids good night, and steps away from the table. Aurora, recognizing that her carefully engineered project may be failing, turns toward the room where Hildegart sleeps. A single, final act ends the dream—Aurora fires, delivering a brutal sequence of shots that end Hildegart’s life. The young prodigy is laid to rest in a glass casket, and her somber procession through the twilight streets of Madrid seals the grim conclusion of a mother’s grand, controversial experiment.
