With a highly romantic sense of adventure, two friends leave their familiar surroundings in Buenos Aires for an eight-month journey. When their bike breaks down, they press on, hitching rides along the way. As they begin to see a different Latin America in the people they meet on the road, the diverse geography they encounter begins to reflect their own shifting perspectives. At the heights of Machu Picchu, the majestic ruins and the extraordinary significance of the Inca heritage have a profound impact on the young men. When they arrive at a leper colony deep in the Peruvian Amazon, the two begin to question the value of progress as defined by economic systems that leave so many people beyond their reach. Their experiences at the colony awaken the men inside them whom they will later become by defining the ethical and political journey they will take in their lives. Based on the journals of both Alberto Granado and the man who would later become "El Che," this film is a journey of self-discovery, tracing the origins of a revolutionary heart.
