In Araruna, a small town in the State of São Paulo, Brazil, circa 1886, Sinhá Moça and republican Dr. Rodolfo are engaged in a forbidden love affair. Rodolfo is fighting slavery and Sinhá Moça, an abolitionist herself, is the daughter of Coronel Ferreira, the Baron of Araruna, a man who is thoroughly pro-slavery. To complicate things further comes Rafael, a former slave who earned his freedom; he is the result of a secret relationship between the Baron and his slave Maria Dolores.
