When evil comes from the blood

An old, gloomy house, three floors of dark secrets. Sofía, a sick little girl, has been at the center of an inexplicable storm since her birth. As tragedy begins to spill over, a strange power takes hold of her, transforming the girl into a threat. At first, her episodes seem like mental disorders, but soon a much more terrifying reality is revealed. Screams, broken glass, and empty stares become omens of something far beyond human comprehension. As the family members dive into the mystery, they realize that Sofía is not fighting a disease, but dark and evil forces that have possessed her. The events intensify, the attacks become more violent, and the girl is no longer just a victim: she has become a being capable of moving mountains with her supernatural strength, a force that threatens not only her mother, but everyone who comes too close. Nothing will be the same in that house. As terror takes over them, the family must face a macabre truth: something else is lurking in the shadows, and Sofía, their own flesh and blood, is being used as its instrument.
