Follow four young, novice adventurers as they embark on one of the most unforgiving treks on Earth, through the Greater Patagonian Trail in Chile, South America. They encounter treacherous rocky mountain passes and dark, dense forests that are almost impassable as they make their way through 3000 kms of untamed land, with 50-pound rucksacks upon their backs. Along the way, they discover a culture bred on this unrelenting land, cherished deeply by those born to it, and the threat of development looming large over what “truly is one of the last wild places in the world.
