The wedding day of Clara and Koldo begins bathed in joy and promise, a celebration of love set in an isolated villa where family and friends gather. The mood is light, laughter and music filling the air as the couple basks in the happiness of their union. A DVD montage opens the film, showing tender moments of Clara and Koldo's wedding, setting a warm tone that soon darkens. Among the guests are Koldo's cousin Adrián, Clara's sister Tita, the wedding photographer Atun, and others like Rafa, Natalie, and a mysterious figure known as SpongeJohn. The old priest, a somber presence, quietly warns, "This is all the beginning of the end," a cryptic hint of the horror to come.

As the festivities continue, an unsettling undercurrent begins to surface. Uncle Victor, Koldo's uncle, starts to show signs of distress after a bite on his hand from an unknown source. His body convulses violently, and he suddenly attacks an aunt, vomiting blood in a grotesque display that signals the outbreak's onset. The villa quickly becomes a prison as the infection spreads, turning loved ones into ravenous monsters. The guests are trapped inside, the doors locked down by authorities who quarantine the estate to contain the outbreak.

Inside the villa, chaos erupts. Clara, initially confused and terrified, witnesses the horrifying transformation of her family and friends. In a harrowing scene, she finds Raga and his girlfriend obliviously having sex downstairs, unaware of the carnage unfolding around them. The infection is not merely viral but supernatural; reflections in mirrors reveal the infected as grotesque, emaciated female creatures, suggesting a demonic possession rather than a simple contagion. The old priest's voice, reciting Catholic Latin prayers over the PA system, temporarily freezes the infected in place, revealing their vulnerability to spiritual forces.

Koldo, determined to protect Clara, arms himself with medieval armor and weapons, embodying a chivalrous knight defending his bride. Meanwhile, Clara transforms from a frightened bride into a fierce warrior, cutting off her long wedding dress and wielding a chainsaw with grim determination. "This is my day!" she declares, revving the chainsaw as she fights through the infected. The villa's kitchen becomes a grim battleground where Koldo discovers Atun, the wedding photographer, dead by suicide--he slit his wrists to avoid turning and killed the Vet with a kitchen tool before dying himself. This grim tableau underscores the desperation gripping the survivors.

Clara, Rafa, and Natalie encounter SpongeJohn in the hallway, a guest now armed and dangerous. Natalie is swiftly devoured by SpongeJohn, who then shoots Clara's infected mother, only to be eaten himself moments later. Rafa and Clara hide in the cellar, the darkness and confinement amplifying the terror as more infected close in. Rafa is bitten during their escape, and in a heart-wrenching moment, Clara uses her chainsaw to end his life before he can transform. The loss fuels her resolve to survive and reunite with Koldo.

Koldo confronts Uncle Victor, the original source of the infection, in a brutal fight that ends with Victor's death. The infected grandfather, however, proves more dangerous. Deaf and thus immune to the priest's paralyzing prayers, he bites Clara, infecting her. In a desperate attempt to save her, Koldo amputates Clara's arm below the elbow, hoping to halt the infection's progress. Despite his efforts, the infection takes hold, and Clara begins to show the first signs of transformation.

The couple makes their way to the estate's exit, only to find it heavily guarded by police and GEO teams enforcing the quarantine. Authorities order Koldo to release Clara, now fully infected, but in a final, tragic act of love, they share a kiss. Clara, consumed by the infection, bites Koldo's tongue off in a savage moment of horror. The infected bride then turns on the armed men, prompting them to open fire. Both Clara and Koldo fall, mortally wounded, yet in their final moments, they hold hands--a poignant symbol of their undying bond even as death claims them.

Throughout the ordeal, the film weaves tension and momentum, shifting between moments of frantic action and chilling revelation. The spiritual nature of the outbreak, underscored by the priest's prayers and the eerie reflections, adds a layer of supernatural dread beyond the typical zombie virus narrative. The villa, once a place of celebration, becomes a claustrophobic arena of survival and loss, its various rooms--from the cellar to the kitchen and garden--stages for the escalating horror and desperate confrontations.
