'Doutor Gama' is based on the life of Luiz Gama, one of the most important characters in Brazilian history. A black man who used the law and the courts to free over 500 slaves. Born a free man, Gama was sold as a slave at the age of 10 as payment for his father's debts. Even as a slave, he learned to read and write, studied and then gained his own freedom, becoming one of the most respected lawyers of his time. He was an abolitionist and a republican who inspired an entire nation.
