Genio is the story of a shepherd, a poor and unschooled Italian boy, caught up in the greatest mass migration in modern history: the emigration of four million Italians to North and South America. Swept along in this flood of humanity, Genio lands in Brazil, and scratches and claws his way to a position of power and influence.
