The story takes place in the mysterious "Casa del Naranjo", the mansion owned by the Olmedo sisters. Each of them has a different character and personality, and at the same time enigmatic: Sara, is very ambitious; Narcisa, honoring her name, is extremely narcissistic, and Dolores, who is a widow and religious fanatic. The Casa del Naranjo works like an asylum, which at first sight has nothing particular, but people do not know that this mansion, being the only source of income for the Olmedo, contains serious secrets and strange events that occur there, and the owners from the mansion they hide it very well, helped by Mr. Fernando Cadena, Sara's husband, who will ensure that the situation continues, because if the truth is known, he would run the risk of discrediting his figure, and with it his ambitious aspiration to occupy an important political position.
