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'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.
The story of the first 2,300 years of humanity and recounts events exclusively from that period. The plot begins by giving us a greater understanding of why we exist and how we turned from perfection to imperfection. The origin of all social and racial problems is there at the beginning of everything, when via one decision a human being who only knew good and enjoyed it so much also chose to know evil.
