No spoilers — just enough to know if this is your film.

Sister Junia is not a woman who fits neatly into the Catholic Church’s architecture for women. She occupies the shadowy margins — doing the hard spiritual work that male clergy quietly delegate when it becomes too dangerous or too inconvenient, then reclaim when the credit is distributed. Trained under the legendary Father Kim, she has stood in rooms where evil was undeniable, and she has not flinched. She carries this experience with the economy of someone who has no time left to waste, because she literally does not — a diagnosis of advanced uterine cancer gives her a horizon she can see from where she stands. In another kind of film, this would be a wound. In Junia’s hands, it becomes something closer to a permission slip.

The inciting event is a collapse. A young boy named Choi Hee-joon — ordinary, quiet, unremarkable in every external respect — has been overtaken by a demon of a specific and terrifying designation: one of the 12 Manifestations, a theological category that carries serious weight in this film’s spiritual universe. The Church’s appointed exorcist has intervened and failed. The designated priest who could handle this level of entity is overseas and cannot return in time. Junia partially suppresses the demon during the chaos, but partial suppression is not deliverance, and the boy is deteriorating inside a Catholic hospital with a bureaucracy more interested in jurisdictional authority than in saving him.

What is at stake for Junia is not merely a child’s survival — it is the entirety of what she has built her life on. The Church explicitly forbids an unordained nun from performing an exorcism; to do so is to place herself outside its hierarchy and to risk everything her faith has given her. There is also the demon itself to consider, which seems to have a specific and personal interest in Junia’s cancer, weaponizing her mortality with the precision of something that knows exactly where a person is most fragile. The stakes are layered in a way that makes the film more than a supernatural procedural: Junia is fighting for the boy, fighting the institution, and fighting her own body simultaneously.

Sister Michaela is Junia’s reluctant partner and her opposite in almost every respect. Where Junia moves with the certainty of someone who has made peace with her course, Michaela is haunted — by a shamanic ability she was born into rather than chose, and by a past tragedy that her abilities contributed to in ways she has never been able to forgive herself for. Father Paolo, the attending physician-priest, represents the voice of rationalist institutional order: a man who genuinely believes medicine is the correct response and views the nuns’ plan as dangerous fanaticism dressed in faith. He is not a villain in any simple sense; his skepticism is sincere, which makes his obstruction all the more frustrating to watch. Then there is Hyo-won, the shaman brought in from entirely outside the Church’s walls — a presence that forces the film to acknowledge that the tools the institution provides may not be sufficient for the battle ahead.

What separates Dark Nuns from the standard exorcism film is that it is not primarily interested in the demon. It is interested in the institution. Most films in this genre ask: can the priest defeat the evil? Dark Nuns asks a more uncomfortable question: why is it a priest at all? The Church’s explicit reservation of exorcism as male-only clergy territory becomes the film’s central dramatic engine — not as an external commentary bolted onto a horror story, but as the architecture of the plot itself. The Korean title deliberately mirrors The Priests (2015) — the same construction, the female religious term substituted for the male one — and that substitution is the film’s thesis stated in its title before a single frame has played.

Director Kwon Hyeok-jae keeps his horror register atmospheric rather than visceral. Jump scares are rationed to the point of scarcity; the tension is built instead through dialogue, institutional obstruction, and the slow accumulation of dread that comes from watching capable people navigate a system that does not want them to succeed. The cinematography has been widely praised for its visual beauty — several sequences feel more like paintings than horror staging — and the film earns its extended exorcism finale through the emotional labor of its first two acts rather than through spectacle alone. For viewers expecting the kinetic horror of something like Train to Busan, the pacing will feel meditative. For viewers who respond to dread as a slow pressure rather than a sharp shock, it lands exactly as intended.

Dark Nuns lands with particular weight against the backdrop of Korean religious history. Korea carries a long tradition of mudang — shamanic practitioners, predominantly women — who have existed in tension with and alongside imported religions, including both Catholicism and Buddhism, for centuries. The film takes this syncretism seriously: Hyo-won’s participation in the ritual is not presented as comic relief or as a threat to orthodox faith, but as a genuine spiritual contribution that the Catholic framework cannot replicate on its own. This connects Dark Nuns to a broader wave of Korean supernatural cinema — post-Exhuma, post-The Wailing — in which the spiritual is treated as inseparable from cultural identity, and in which the intersection of Korean shamanism and Western religious tradition produces something neither tradition could have generated alone.

Full spoilers ahead — what happens, what it means, and what the demon got wrong about Junia’s body.

The exorcism succeeds — at a cost only Junia could have chosen to pay. In the film’s extended climax, Sisters Junia and Michaela conduct the forbidden rite with Hyo-won’s drumming and chanting running parallel to the Catholic ritual. A Rosicrucian priest arrives from Italy — dispatched by a sympathetic Church faction — and grants the nuns formal authorization just in time to remove the last institutional barrier. The demon is expelled from Hee-joon’s body after a prolonged and physically devastating ritual. The boy survives. Gang Dong-won’s Deacon Choi appears in a brief cameo, threading this film back into the shared universe of The Priests. What happens next is the ending’s real argument.

The demon is not destroyed. It is contained — inside Junia’s cancerous womb. In The Priests (2015), the expelled entity was trapped in a pig, a direct echo of the Gadarene swine passage in the Gospels. Dark Nuns replaces the pig with a woman’s dying body. The film is completely aware of what it is doing with this parallel. A surface reading equates Junia with the pig — a vessel for something unclean — which has led some critics to argue the film inadvertently undermines its own feminist premise at the moment of resolution. But the more defensible reading is the opposite: Junia chose this. Her cancer, which the demon had been weaponizing against her throughout the film — taunting her with her own timeline — becomes the very thing that makes her the ideal prison. The body the Church said was unfit to perform the sacred rite turns out to be the only vessel powerful enough to hold the demon that defeated every ordained alternative.

The ending poses questions it refuses to answer, and they are the right questions. Whether Junia survives her cancer after containing the demon — or whether the containment somehow alters the progression of her illness — is deliberately left unresolved. Whether the demon remains contained after her death, or whether the Church has a plan for what comes after, is equally open. Some viewers read the ending as tragedy sharpened by irony: a woman sacrifices herself to do a man’s job and is rewarded with a demon inside her dying body. Others read it as triumph: the sacrifice was deliberate, the agency was hers throughout, and her dying body accomplished what the institution’s authorized instruments could not. A third reading focuses on the syncretism: the exorcism only succeeds with the shaman present, suggesting that no single tradition has exclusive access to this kind of power.

KDW verdict: the ending is a consummation, not a punishment. The film spends 114 minutes cataloguing every way Junia’s body has been told it is insufficient — female, unordained, cancerous, dying. The ending inverts this entirely and retroactively. The demon that taunted her with her cancer was revealing its own fear, not just its cruelty: it understood what she was capable of even when the Church did not. In The Priests, the demon ends up in a pig. In Dark Nuns, the demon ends up in a woman who chose to be its prison. That is not an accident, and it is not a diminishment. The Church told Junia what her body could not do. Her body ended up doing the one thing no one else could.

What you notice on rewatch. Junia’s response to her cancer diagnosis in the early scenes — detached, almost administrative — reads entirely differently once you know the ending. She is not in denial; she has already decided what her remaining time is for. Her willingness to take on the forbidden exorcism is not impulsive heroism. It is a plan. Every moment where Father Paolo insists on medicine over faith stops looking like rational skepticism and starts looking like a man who cannot conceive of a woman’s body as a site of spiritual power. And every time the demon uses her cancer against her, it is — in retrospect — demonstrating that it already understands the threat she represents better than the institution that trained her ever did.
