After years of quiet, Ed and Lorraine Warren are pulled out of semi-retirement when a desperate call comes from a small Irish village plagued by an unexplainable series of violent deaths. The locals believe the ancient veil between the living and the dead has been torn open, letting something unspeakable slip through. Despite Lorraine’s frail health and Ed’s aging heart, they agree to investigate—drawn by the disturbing similarities to a case they buried decades ago.
Upon arrival, the Warrens are met with a wall of silence. The townspeople are superstitious and terrified, believing the deaths are punishments tied to a cursed abbey deep in the forest. Local lore speaks of a 15th-century order of monks who attempted to open a “gateway to God” but instead invited the devil himself into their sanctuary. The abbey was sealed—and forgotten—until recent construction disturbed its foundation.
As Lorraine begins to experience intense visions of burning monks and screaming shadows, Ed uncovers a chilling truth: the abbey was not merely haunted—it was a trap for a demonic entity named “Vargan,” an ancient spirit of possession. Now free, Vargan is weaving its influence through the town, corrupting the minds of those who are weakest and slowly feeding on their souls.
The Warrens team up with a skeptical Irish priest, Father Callahan, and a grieving woman whose son was one of the victims. Together, they explore the abbey’s underground chambers, where time itself distorts and the walls seem to whisper. Lorraine, with her clairvoyant sensitivity, becomes the entity’s main target, as Vargan seeks a host powerful enough to transcend the veil completely.
Haunted by ghostly monks and visions of an apocalyptic ritual, Lorraine is pushed to the brink of madness. Ed, meanwhile, discovers a forbidden exorcism rite buried in Vatican archives—one that was deemed too dangerous to ever be performed. As the spiritual attacks intensify, the Warrens must decide whether to risk everything by using the dark rite or allow the demon to consume the village and possibly the world beyond.
In a terrifying climax beneath the ruined abbey, Lorraine confronts Vargan in a psychic battle that takes her to the edge of death. Ed, risking his own life, performs the forbidden rite, guided only by faith and desperation. The entity is finally cast back through the veil—but not before it brands Lorraine with a mark, hinting that its connection to her is not entirely severed.
Back in America, the Warrens lock away the abbey’s relics in their artifact room. But Lorraine begins to have dreams again—of fire, shadow, and a voice calling her name. The final scene closes on her reflection in a mirror… where something watches her from the other side, smiling.
