The abolition of the Salic law in articulo mortis and the arrival to the throne of Elizabeth II unleash the conflictive 19th century in Spain, full of fratricidal wars, conspiracies, and mysteries. In 1882, Isabel II lived her Parisian exile in the palace of Castile, among nobles and tinsel but now far from power. An attractive gentleman will arrive at that Elizabethan court, Julio Uceda, sent by Sagasta with compromising documents for the queen, and also Teresa, a young woman raised and educated in the Leganés Girls, a school for orphans in Madrid, whose vision of the world is far from life in the palace, too far removed from the underprivileged. Between them, a love passion will emerge that must navigate between political conspiracies and the suffocating and corrupt environment of a monarchy in decline, where nothing is what it seems, but at the same time, everything is as hypocritical and corrupt as it appears.
