A family embarks on a journey to Italy to claim an ancient inheritance. John, the father, is a recovering alcoholic struggling to keep his life in order after a series of traumatic events and a family crisis. Along with him are his wife and their perceptive but restless daughter, Beck, who find an isolated and crumbling castle that seems pulled from a gothic novel. Upon arrival, they realize that the place is filled with mystery and dark secrets.
As they try to adapt to their new home, they discover that the castle is not as uninhabited as it first appeared. In the shadows, a sinister presence lurks: a deformed and terrifying being that has been kept in darkness, a prison that is both physical and psychological. As tension mounts, the family faces palpable fear when they begin to experience unsettling phenomena and things start to disappear from their surroundings.
As the mystery of the ancient castle deepens, disturbing revelations about its history and the reason behind the presence within its walls emerge. The struggle for survival turns into a terrifying game, where each family member must confront their own inner demons and the imprint of a dark past they are not prepared to face. Thus, the castle becomes the stage for a descent into madness and horror, where nothing is as it seems.
