The life of Silvino Santos (1886-1970), a Portuguese man who fell in love with the Amazon River. At thirteen, Silvino crosses the Atlantic at the turn of the century in search of that fantastic Amazon imagined by Europeans. In 1913, he made his first feature-length documentary. He would live his adventure against great personalities, witnessing remarkable events, from the splendor to the fall of the rubber monopoly. Filming this Amazon from the beginning of the century, he becomes a jungle myth and one of the pioneers of cinema in Brazil.
