Sister Death

In 1939, a Spanish town is captivated by a young girl believed to possess holy visions, a legend that nourishes the faith of the locals and casts a gentle, almost ceremonial light on everyday life. A decade passes, and the war’s scars begin to fade into memory as a convent is reimagined into a school for girls in the wake of the Red Terror. Into this transformed place arrives Narcisa, welcomed by Sister Julia and the Mother Superior, who is eager to elevate the tale of the “holy girl” to the forefront of their community. The Mother Superior explains that Narcisa will take over teaching duties that once belonged to Sister Inés, who has already left the convent behind.

In her new room, Narcisa stumbles upon the unsettling relics of the past: a cigar box filled with letters, a pair of scissors, and a faded funerary photograph of Sister Socorro. Almost immediately, she is drawn into a world where the line between the living and the dead begins to blur. Night after night, disturbing phenomena intrude upon her routine: a chair seems to fall on its own, an incomplete hangman’s drawing decorates the wall, and, frighteningly, a student reacts with terror simply because Narcisa writes her name on the blackboard. During confession, Narcisa opens up about her insecurities—her supposed supernatural gifts and the weight of her faith—setting the tonal stage for a slow-burn fright that never relies on cheap shocks.

The tension escalates when two girls discover the very scissors from the cigar box in the convent’s bathroom, and a supernatural encounter follows. Sister Julia dismisses the girls’ fears and even disciplines one of them, Rosa, for causing trouble. Narcisa visits Rosa in confinement hoping for answers, and Rosa speaks of a vengeful presence she calls “the girl.” Rosa explains that a curse is attached to a name written by this spirit on the blackboard, a curse tied to the past abductions and betrayals that led Sister Inés to flee years before.

A moment later, Rosa’s name appears on the board, confirming Narcisa’s fears and prompting a desperate attempt to communicate with the spirit. The two of them team up to complete the hangman drawing, and a shadowy presence seems to linger just out of sight as Rosa senses something otherworldly behind Narcisa before she vanishes. In a frantic search through the convent, Narcisa faces a terrifying encounter in the confessional booth before discovering Rosa murdered, her body found behind the lattice as the community mourns in shock.

Sister Julia quickly assigns blame to Narcisa for the tragedy, and the newly drawn line between fear and accusation threatens to fracture Narcisa’s already fragile sense of purpose. The young teacher decides to leave the convent, but a troubling solar eclipse traps her in place. As the moon darkens the sky, Narcisa gazes upward and experiences a trance-like vision that reveals the convent’s long-buried past—war-era plunder and sexual violence that have haunted its walls for decades.

Back in the quiet of her room, Narcisa is confronted by the spirit of Sister Socorro, who appears through visions that feel both intimate and terrifying. Socorro’s revelation is stark and painful: she was raped during the war and conceived a daughter, a secret the other nuns swore to keep. When the child fell ill years later, Socorro urged taking her to a hospital, but the nuns chose to safeguard the family secret and locked Socorro in her room while moving the child toward the bathroom. The child’s fever rose, and in the struggle to force Socorro’s daughter into the bath, tragedy struck, the young girl dying after hitting her head on the tub. Grief gave way to despair as Socorro learned of her daughter’s death, and she hanged herself in Narcisa’s room, sealing the sorrow into the convent’s history.

Narcisa’s encounter with Socorro’s spirit becomes a catalyst for a furious, otherworldly reckoning. Socorro’s presence is unleashed, and it exacts vengeance on the two nuns who betrayed her memory—Sister Julia and the Mother Superior—killing them both. In the aftermath, the spirits of Socorro and her daughter are shown finally reuniting in the bathroom, a haunting denouement that binds past and present in a single, spectral moment.

Many years drift by, and an elderly Narcisa now teaches a new generation of girls, who mockingly nickname her “Sister Death” as a reminder of the haunting she has carried with her for decades. The classroom becomes a place where memory and fear mingle, and among the students a young girl named Verónica crosses Narcisa’s path, hinting at the enduring imprint of the past on those who survive it. The film closes on this quiet, unresolved note: a life-shaped by revelation and revenants, where the line between spiritual visitation and personal history remains thin, fragile, and unforgettable.
