What Is The Nun About?
The premise of The Nun in 334 words, with nothing given away. The full story follows below.
A dark cloud hangs over the hallowed halls of a once-feared Catholic boarding school, where whispers of an unspeakable past still echo through its corridors. Years after a cruel and merciless nun turned the institution into a place of terror before vanishing without a trace, a new generation of students — and the survivors who once walked those halls — find themselves haunted by what was left behind. The story lingers in the space between memory and nightmare, where old sins refuse to stay buried.
Eve, a young woman whose life has been shaped by the shadow of that long-ago tragedy, steps into the mystery when her mother, Mary, becomes the first of the former students to meet a brutal end. Driven by grief and a desperate need for answers, Eve travels to the school, determined to uncover the truth behind the wave of strange deaths now claiming the women who once defied the tyrannical nun. As she digs deeper, she joins forces with the remaining survivors, a tight-knit circle bound by a decades-old secret and the terrifying knowledge that they are being hunted one by one.
The film unfolds with a creeping sense of dread, weaving together the atmospheric gloom of gothic horror with the personal stakes of a daughter piecing together her mother’s hidden history. The boarding school itself becomes a character — its faded grandeur and sacred spaces now tainted by the violent spirit that once ruled them. Each clue Eve uncovers brings her closer to the other women who share her mother’s past, even as a sense of impending doom tightens around them all.
What emerges is a tense tale of inherited trauma and the inescapable pull of the past, where faith, guilt, and the bonds of old friendship collide with an evil that refuses to rest. Eve must navigate a web of silence and suspicion, confronting not only the malevolent force stalking her mother’s friends but also the unsettling possibility that some truths are more terrifying than any ghost.

Spoilers ahead
An insane nun, Sister Ursula, strikes fear into the hearts of her students at a Catholic boarding school. The story takes a dark turn when one of the girls, Mary, is revealed to be pregnant by an influential figure affiliated with the institution. With malicious intent, Ursula uncovers Mary’s secret and attempts to force her into an abortion using a makeshift device in the school’s bathroom. The situation escalates as Mary’s friends come to her aid, confronting the nun and ultimately causing her to stumble, hitting her head and falling into a bathtub filled with water.
The girls choose to leave Sister Ursula in a pond, which had been blessed by priests, and vow to keep the incident a secret. Describing these events as a tragic misunderstanding, the authorities of Barcelona simply report the nun missing. Fast forward eighteen years, the pond is drained, and the vengeful spirit of Sister Ursula is freed from her watery confines, ready to exact revenge on the girls who played a part in her downfall.
The narrative intensifies as a young girl named Eve arrives at the boarding school following the brutal murder of her mother, Mary. Driven by a desire for answers, she connects with other survivors of the past events. Together, they fight against Ursula’s spirit while racing against time to find a way to banish her for good. Eve’s journey becomes increasingly perilous when she witnesses an apparition committing the gruesome act of slitting her mother’s throat. Joining forces with an old friend of her mother’s, Christy, they dive into a dangerous investigation.
The situation escalates when Joanna, another survivor, is discovered dead in London, deepening the suspicion that the events of their past are merging with their present—turning into a deadly re-enactment of the horrors they created. As Eve investigates, she uncovers an affectionate love letter addressed to her mother from someone named Miguel, which leads her to search for other survivors and warn them before it is too late. Her quest takes her to a Special Theological Institute to access the archives of the now-closed boarding school, where she unravels dark secrets.
During her endeavor, she meets Gabriel, a young man studying to become a priest. Gabriel assists her in translating old documents, ultimately revealing the address of another survivor, Eulalia. Tragically, it becomes evident that they are running out of time as Eulalia meets a horrific fate, crucified in her own bathroom by the nun’s malevolent spirit. While Eve perceives Ursula as the murderer, Mary’s past friends, Susan and Zoe, argue against it, adamant that they sealed the nun’s fate long ago.
In a poignant moment, Eve discovers a Bible in Ursula’s former quarters, dedicated to her by a priest named Father Miguel. As Eve and Gabriel share a brief romantic encounter, the ominous presence of the nun manifests, leading Eve to experience haunting visions of her mother speaking to Miguel. Gabriel reveals that the women currently facing danger share names with Catholic saints, establishing a horrific pattern where the women’s fates echo the martyrdom of those saints.
The tension thickens as Susan accuses Eve of being the source of their troubles, dubbing her “the sin” Sister Ursula sought to eradicate. The ensuing chaos reaches a peak when the nun decapitates Susan. In a shocking twist, Zoe reveals to Eve that her father is actually Father Miguel. Conclusively, Gabriel theorizes that the nun can only be vanquished in water and must meet her end as St. Ursula did—with an arrow through her heart. In a desperate attempt, they craft an arrow to fire at the nun’s spectral form. However, time runs short and the effort fails to save Zoe, leading to her tragic death in a raging oven, while Gabriel also suffers a fatal blow from the supernatural force.
In the climactic final act, Eve takes a bold step by submerging herself in a flooded room, armed with the gun. Joel confides in Julia, sharing his unsettling theory that Eve might have been aware of her own connection to the past all along. As the truth begins to surface, it becomes evident that Eve’s mother and her friends may have committed the ultimate act of revenge against Sister Ursula, and as Eve dives deeper, she ultimately faces the grave danger posed by her own weapon. The narrative builds towards a thrilling and tragic conclusion, leaving viewers to reflect on the intertwined fates of these characters.
