Donatela and Flora, two friends who became rivals. One of them committed a homicide and pretends to be innocent. There are two versions for the same story. Who, after all, is telling the truth? Donatela or Flora?

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.
