A god named Kiddo Safia Oakley-Green crafts the world as a tranquil garden and leaves it to its inhabitants to steward. Her father, Birdman Richard E. Grant, steps in to impose order, drawing up a social code that governs life there, including rigid expectations around marriage and gender. Under these rules, Agnes bears a daughter, Hero Emma Corrin, and a line is drawn between freedom and conformity that threads through the generations.
Twenty-seven years pass, and Cherry Maika Monroe finds herself trapped in an unconsummated marriage with Jerome Amir El-Masry. Pressure from Jerome’s clan to produce an heir grows, but he continues to avoid consummation. Cherry is given a stark ultimatum: become pregnant within one hundred days or face death. Jerome turns to the enigmatic Manfred Nicholas Galitzine, who swears he can test Cherry’s loyalty by wooing her. The two men strike a dangerous bargain: Manfred has one hundred nights to win Cherry’s heart, and if he succeeds, he will inherit Jerome’s estate; if he fails, the debt will be paid in blood—the pair of conditions that set the castle on edge.
Jerome departs on business, leaving Cherry under Manfred’s watch with a cohort of guards and her maid, Hero. Manfred presses his advances, but Cherry resists, turning to Hero for a lifeline. The two forge a secret code: when Cherry wants to escape Manfred’s circle, Hero will tell stories that open a path home. Hero begins to recount the tale of three sisters—Mina Kerena Jagpal, Caterina Olivia D'Lima, and Rosa Charli XCX—whose father arranges marriages after their mother dies. The sisters secretly learn to read and write, a dangerous act in their world. Rosa’s marriage eventually reveals the discovery of her writing, leading to accusation, arrest, and, ultimately, execution. The sisters choose to leap from a cliff rather than renounce their voices, and their father recovers their bodies, capturing and disseminating their story as a beacon of subversive literacy.
As Cherry endures the mounting anxiety of the countdown and Jerome’s quiet absence, Manfred’s pursuit intensifies and tension flares with Hero. Cherry, craving closeness, kisses Hero, and the moment opens a deeper conflict when she learns Hero can read and write. To fulfill the bloody bargain, Cherry agrees to conceive a child with Manfred. Just as the clock runs out, Jerome returns and proclaims that the hundred nights have ended, declaring Manfred the winner and ordering Cherry’s confinement to prevent charges from being filed. Manfred resists the outcome, insisting he intends to stay with Cherry.
Hero steps forward to take responsibility for shaping Cherry through the forbidden stories. Cherry speaks openly of her love for Hero and acknowledges that the stories have altered how she sees her life. Jerome accuses Hero of witchcraft and calls for punishment, while Hero explains that her mother, Agnes, was part of a secret effort to preserve stories through tapestries. A maid named Wilmot Clare Perkins hides stories throughout the castle, and Hero arrives as a maid to salvage them; she stays, continuing to write after Wilmot’s death, compelled to keep the narratives alive.
The conflict escalates to charges of witchcraft and perversion, and Cherry and Hero are condemned to death. As Hero’s writings circulate, public sympathy swells and guards who uncover the hidden works share them with the crowd. A vast assembly gathers to witness the execution, and when offered mercy in exchange for confession, Cherry and Hero refuse. They leap from the execution site, choosing resistance over surrender. Their bold act sparks a broader awakening: storytelling, long guarded by women, begins to spread. In a final, supernatural turn, Cherry and Hero endure and are transformed into constellations—the Heroes who illuminate the night sky and the enduring power of storytelling.
