In a quiet suburb of New York, the Montelli family moves into an old house that will soon reveal a dark secret. The Montellis, consisting of young Andrew, his parents, and his sister, feel a strange attraction to their new home but also a growing unease. From the very first day, a disturbing sensation envelops the house, and inexplicable events begin to occur.
Andrew, a charismatic teenager, starts to change his behavior; his attitude becomes increasingly aggressive and volatile as a powerful demonic force seems to take hold of him. Amid these tensions, the family faces internal struggles: an authoritarian father, a mother trapped in her own drama, and a sister seeking love and acceptance. As the supernatural influence intensifies, Andrew finds himself caught in a whirlwind of possession.
The situation becomes unsustainable when violence reaches its climax, shattering everything they know and leaving a trail of horror in its wake. The story culminates in a devastating confrontation where Andrew is forced to fight against the demon that inhabits him, while his family crumbles under the weight of madness and terror. In this clash of light and darkness, lessons about love, guilt, and sacrifice intertwine with the supernatural, turning the house into a true hell.
