In a feature-length special shot on location in the Brazilian rainforest, we recount the story of intrepid adventurers who tried to tame the Amazon, and investigate tales of heroism, greed, and death in this hostile region. From Theodore Roosevelt to Henry Ford to Hiram Bingham, who uncovered Machu Picchu, we travel through time along this magnificent river, and meet unsung hero Walter Earnest Hardenberg, whose bravery brought one of the most harrowing tales of human torture in the 20th century to world attention. We also join ethnobotanist Richard Evans Schultes, who embarked on an adventure to seek the botanical source of a plant known as curare, a muscle relaxant that's derivatives are used in surgery today. The Amazon has challenged these adventurers to perform acts of almost superhuman endurance, inspired folly in the cautious, bravery in the coward, and brought great men to their knees. (shot in HD)
