Dakota Blue Richards stars as Maria Merryweather, a spirited girl who inherits a mysterious book called The Ancient Chronicles of Moonacre Valley after her father’s death. The book tells a long-forgotten legend about the Moon Princess, who receives magical pearls from the moon. In the old tale, the Moon Princess weds into the Merryweather family, while her father, a de Noir, gifts the couple a black lion and the bride’s husband gifts her a unicorn. When the princess reveals the pearls, both the de Noirs and the Merryweathers are struck by greed, a greed that taints the valley and foreshadows a curse that could last for generations. The tone of the chronicle is careful and dreamlike, hinting at a world where magic and history collide.
Dakota Blue Richards’ Maria is soon forced to leave her London life behind with her strict governess, Miss Heliotrope, and travel to Moonacre Manor to live with her estranged uncle, Sir Benjamin Merryweather. Miss Heliotrope offers quiet guidance as the two step into a sprawling estate steeped in old feuds. Sir Benjamin, a stern yet protective figure, warns Maria about lurking bandits in the forest and cautions her to steer clear of the rival de Noir family. The tension is palpable as the two worlds—the sleek city and the wild, rumor-haunted woods—collide at the edge of the manor’s gates. In the shadows of Moonacre, a menacing sense of history repeats itself, and the air feels charged with secrets waiting to be unearthed.
In the forest, danger comes quickly. Maria glimpses a cry for help and soon finds herself surrounded by bandits, only to be saved by a fierce, loyal presence: Sir Benjamin’s black dog, Wrolf. The encounter deepens Maria’s curiosity about the family feud and the mysteries that haunt Moonacre Valley. As the story within the book comes alive, she learns that the Moon Princess’s tale lives on in their world, and that the two families’ quarrel is not merely old gossip but a live, breathable curse that threatens everyone who loves Moonacre. The book also reveals a prophecy tied to the “pure heart” needed to lift the darkness at the rising of the 5000th moon, a moment that draws increasingly near.
A pivotal figure emerges: the revelation of who holds the pearls and where they are hidden. The chronicle hints that the casket containing the pearls has been stolen by the de Noirs, while the Merryweathers possess the key that unlocks their fate. Maria’s journey becomes a blend of courage, investigation, and a growing sense of destiny as she uncovers that she is the embodiment of the Moon Princess the tale describes. An encounter with the fortress and its guardians leads to a tense exchange where clues, deception, and loyalty collide. Along the way, she learns more about Loveday, a woman who once loved Sir Benjamin and who is later revealed to be connected to the de Noirs in a painful backstory that tests the values of forgiveness and reconciliation.
Loveday becomes a crucial figure as Maria discovers more about the past. The two arc toward a complicated truth: Loveday and Sir Benjamin were once betrothed, but a revelation forced Loveday to leave, setting off a chain of events that still echoes through Moonacre. Through paintings and whispers, Maria pieces together where the pearls are hidden and why the casket has remained empty. She even forges letters to draw Sir Benjamin and Loveday into a meeting, hoping to mobilize Robin—a bold ally she has met, played by Augustus Prew—to join in her plan. The tension escalates as Loveday and Sir Benjamin realize Maria’s deception, and the search broadens to include Miss Heliotrope, Marmaduke, and Digweed, a loyal servant whose loyalty becomes a quiet anchor in the unfolding drama.
In the forest, the quest intensifies. Maria and Robin De Noir team up to locate the pearls, eventually discovering them inside a hollow tree and slipping away through a hidden tunnel. The pursuit by Coeur de Noir’s men grows fiercer, and tragedy strikes as Wrolf dies while defending the pair, a loss that underscores the peril of the feud. Coeur reaches the cliff where the curse is set to awaken with the moonrise, just as the tide of fate seems poised to overwhelm Moonacre. Sir Benjamin arrives with Digweed and Marmaduke in tow, followed closely by Maria and Robin, and the tension between the rival factions culminates in a dramatic, crowded confrontation. Loveday, who unveils a surprising kinship with the de Noirs, also arrives, shifting the balance of loyalties.
Maria, desperate to redeem the valley, confronts a hard truth: simply uniting the families may not be enough to break the curse. She realizes that the change must come from within her own heart, and she makes a courageous choice to sacrifice everything she holds dear. In a stunning sequence, she plunges into the sea with the pearls. A mighty wave carries her toward the cliff’s edge, and she returns not as a victim but as a symbolic guardian of Moonacre’s future. She emerges riding the back of a white unicorn, a powerful embodiment of hope and renewal, while a resurrected Wrolf reappears in his true form—the black lion—signaling a restored balance between the forces that once divided the valley.
In the aftermath, the families begin to reconcile. Sir Benjamin and Loveday step back from old resentments, and Miss Heliotrope arrives to witness what might be Moonacre’s turning point. The Moonacre valley is restored to its former wonder, the curse lifted, and the bonds between the Merryweathers and the de Noirs are renewed. The tale ends with a quiet faith in forgiveness and the enduring power of a pure heart, as Moonacre returns to a state of harmony where magic can flourish and old wounds have a chance to heal.
