Gracíela Mendoza, the eldest daughter of the Mendoza ducal house, is executed by beheading alongside her younger brother after her father dies of illness and her uncle tricks her out of the family estate, frames her for crimes, and seizes power. She then inexplicably returns to five years earlier, retaining all memories of her past life. Determined to avoid the same tragic fate, Gracíela buys the legal identities of a noble mother and child and disguises her brother as her own son, fleeing to a neighboring country to survive. The story follows her struggle to build a precarious new life while hiding their true identities, navigating the political and social dangers of a foreign court, and slowly unraveling the conspiracy that destroyed her family. Key characters include Gracíela, a resourceful and resilient protagonist; her young brother Florenci, who must adapt to life as her supposed son; and a spider spirit named Gacchan who aids her. The setting is a fantasy kingdom with rigid noble hierarchies and neighboring nations where Gracíela must forge alliances and tread carefully. Notable narrative arcs include the initial escape and identity establishment, a mystery involving the apparent suicide of a marquis's granddaughter that Gracíela investigates, and the gradual confrontation with the uncle's schemes and the hidden truths behind her father's death.
