In the premiere episode, a hunter and a farmer pool their knowledge as they attempt to survive 21 days in South Africa. But when the wildlife proves too stealthy to hunt, the survivalists take a life-threatening risk for food.

In this all-female tribe's challenge, two veteran survivalists return to mentor two newcomers on the perils of San José Del Guaviare, Colombia, for 21 days. But scarce food resources and torrential tropical storms take a quick toll.
