Steve and a team of climbers and jungle survival experts head into the ancient landscape of South America's Guiana Shield. This vast wilderness of pristine forests and towering table-top mountains is one of the most inaccessible terrains on the planet. Early explorers came here in search of gold and many never returned. Today there are reports of a new gold rush. With the help of local contacts, Steve gains access to an illegal gold mine and meets the modern-day prospectors. With the future of these jungles under threat, Steve's goal is to push deeper than ever before to explore this lost world of undiscovered natural riches and stunning wildlife.
