In 1856, the emperor Dom Pedro II lived a marriage of appearances with Teresa Cristina, with whom he was forced to marry at a young age by his parents' political alliance, having two daughters with her: Isabel and Leopoldina. He truly loves Countess Luisa, a cultured and time-ahead woman who fights for the abolitionist cause and women's rights, married to Eugenio, the emperor Napoleon's cousin. At the same time there are sisters Pilar and Dolores: the first went to a convent after her mother's death in childhood, growing up among books and dreaming of studying medicine - inspired by the story of Elizabeth Blackwell, the first doctor in the world -, while the second stayed at home to take care of her father, Colonel Eudoro, growing up repressed, illiterate and without vanity.
