After the sudden death of his twin sister, student Luis returns home for a funeral. It is claimed that the girl died of illness, but she is buried in a closed coffin. On the first night, the guy sees, hears, and feels the presence of otherworldly forces in the house: the dead sister appears and cries that her brother betrayed and abandoned her. The other day, a strange woman warns Luis not to stay in the house, and although his father insists on leaving, the boy decides to stay and figure out what is going on.
