What Is Scarlet About?

The premise of Scarlet in 278 words, with nothing given away. The full story follows below.

In a shattered 16th‑century Denmark, the kingdom trembles under the weight of endless conflict. Noble houses clash, cities groan beneath famine, and the very air feels heavy with the echo of old songs about honor and betrayal. The world is painted in muted stone and blood‑red sunsets, where every corridor of a palace might hide a whispered conspir­acy and every battlefield offers a chance for fleeting glory.

Scarlet, the king’s only daughter, has been raised among silk and ceremony, yet the loss of her father drives her to the clang of steel. Trained in the art of swordplay, she moves through the court and the ruins with a quiet ferocity, her heart a battlefield of grief and a burning promise of vengeance. The film follows her as she steps beyond the gilded walls, confronting hostile forces that test both her skill and the resolve that fuels her quest.

Across the veil of time, Hijiri appears—a young man whose origins lie far from the soot‑stained streets of medieval Denmark. His modern compassion and unguarded optimism cut through the prevailing darkness, offering a stark contrast to the princess’s hardened purpose. Their unlikely companionship becomes a subtle counterpoint, suggesting that hope can arise even in the most desolate of landscapes.

The tone balances grim realism with a mythic undercurrent, weaving sword‑clashing action with moments of quiet reflection. As Scarlet traverses war‑torn roads and forgotten ruins, the story hints at deeper questions about forgiveness, identity, and the possibility of a future untethered from vengeance. The world feels both ancient and strangely timeless, inviting the audience to wonder whether a single spark of empathy can reshape a kingdom drowning in its own shadows.

Spoilers ahead

Princess Scarlet, Mana Ashida, is pulled into a sprawling, Hamlet-inspired saga that blends a queenly Denmark with a perilous underworld and a present-day frame. In this world, Scarlet is the daughter of a beloved king, Amleth, whose rule is challenged by his ruthless brother, Claudius, who seeks not only the throne but the heart of Scarlet’s mother, the vain Gertrude. When Claudius believes Amleth betrayed the realm, he sentences him to death. Before the execution, Scarlet watches with horror as her father speaks his last words, though she cannot hear them; Claudius is crowned, and his rise sows fear and hunger across the land.

Scarlet refuses to let the trauma define her. She trains relentlessly in swordsmanship, driven by a fierce need for vengeance. At a critical ball, she confronts Claudius—a tense, swift exchange—only to be drawn into a ploy when wine is spiked to kill the king. As the night ends, Scarlet finds Claudius in the hall and, with a blade in hand, attempts to strike him down. But the drink reveals itself to have poisoned her instead, and she collapses as Claudius laughs. The vow for revenge burns bright, even as she slips into a perilous new realm of existence.

Scarlet awakens in the underworld, a liminal space where the living and the dead coexist. An ancient, enigmatic old woman explains that Amleth has become ash, a nothingness, while her uncle remains partly alive but not fully among the living. Fear and fury surge through Scarlet as she battles revenant knights who try to capture her for transport to the Infinite Land, a realm where the dead live anew. With armor and swords scavenged from fallen knights, Scarlet fights her way through, aided by the old woman’s guidance, and escapes into the night with the help of a fearless rescue.

In the present day, a paramedic named Hijiri—a man who has become disoriented by this strange world—encounters Scarlet and must be convinced that he is truly dead. Scarlet’s claim that he belongs to the underworld meets his stubborn disbelief, but as more soldiers close in, she shows her prowess in combat, fending them off until she and Hijiri cross paths with Cornelius, one of Amleth’s assassins. A pivotal moment comes when Hijiri retrieves a bow and arrow and uses a whistle to distract Cornelius, allowing Scarlet to wound him in the leg. Hijiri then becomes a reluctant ally, nursing Cornelius back to health and pressing Scarlet to reveal where her uncle might be headed—the Infinite Land.

Along the journey, an elderly caravan—robbed by bandits—crosses their path. Hijiri pleads for mercy, but danger escalates as a dark bolt of lightning disintegrates the caravan master, and a dragon-like presence haunts the skies. The pair are welcomed by the elderly travelers, who are charmed by Hijiri’s care and by Scarlet’s resolve. A moment of cultural bonding emerges when the pair share a dance—an intimate conversation with a god through movement rather than words. The elderly are grateful, but danger remains, as Voltemand and his allies threaten their progress. When Voltemand corners Hijiri and Scarlet, Claudius’s war drums echo through the clouds and the world around them seems to tilt toward the Infinite Land. Scarlet’s arm is wounded, yet she presses on, with Hijiri tending to her and steering them toward safety.

The pursuit intensifies as Voltemand and his soldiers collide with Scarlet’s band. Polonius, one of Amleth’s killers, and Laertes, another hunter of Scarlet, close in. The fight ends with Cornelius killing Polonius using a hidden sword, and Laertes falling to Voltemand’s gun, prevented from firing by Voltemand’s counterstrike. Cornered at the summit, Scarlet learns that Claudius has found a route to the Infinite Land via a celestial stairway, and she and Hijiri push forward with renewed urgency.

At the gates of the Infinite Land, Claudius confronts his own sins and is barred from entry. Scarlet, driven by anger and a desire for retribution, raises her blade again, but a higher moral voice interrupts—her father’s appeal to forgive. In that moment, Scarlet falters, hearing a spectral version of Amleth urging her to choose life over vengeance. The moment is charged with a haunting, ethereal vision of her father asking her to live a brighter future. The gate’s power sparks, and Claudius’s fate is sealed not by a single strike but by the dragon’s fury, which strikes him down as if the heavens themselves condemn him.

Hijiri and Scarlet reconcile their fates in the wake of the gate’s drama. The old woman returns to explain that only one of them can return to the world of the living. Scarlet pleads for Hijiri to come back, but she learns that Hijiri has already died in the present day, having been stabbed by Rosencrantz during a prior confrontation. In a tearful farewell, Scarlet offers Hijiri a final kiss as he disintegrates and she steps back into the living world.

Back in Denmark, Scarlet regains consciousness from the poison’s grip, an antidote restoring her. She learns that Claudius has died from the same poison she drank—a cruel mirror of fate. Gertrude mourns her husband and blames Scarlet for surviving, but Scarlet chooses a different path: she rises as Denmark’s new queen and pledges to build a future free from war, a realm of love and harmony. As she speaks to her people, Scarlet looks toward the sky with a quiet, hopeful smile, knowing that her life’s mission has shifted from revenge to peace.

Themes

What Are the Themes of Scarlet?

3 ideas the story keeps returning to, among them Revenge, Death and Otherworlds.

  1. 01

    Revenge

    Scarlet's arc begins with a burning desire for vengeance after her father's murder and her mother's complicity. The plan to kill Claudius propels her through battles, poison, and political machinations. At key moments, visions of her father and calls for forgiveness shift her toward a future where revenge is no longer the only answer.

  2. 02

    Death

    Death dominates the narrative, as Scarlet moves between the underworld and the living world, confronting mortality and guilt. Hijiri's unexpected demise reinforces that life and death are intertwined rather than discrete. The dragon-like omens and the choice to forgive frame death as a doorway to growth rather than finality.

  3. 03

    Otherworlds

    Mythic realms structure the plot: the underworld, the Infinite Land, and celestial gates that test Scarlet's resolve. The living and dead navigate a shared cosmos that blurs moral boundaries, forcing protagonists to confront their choices. Forgiveness and mercy become lit paths that can outshine vengeance across worlds.
