Overview: Dropped deep in the foothills of the Andes, in Argentine Patagonia, Ed faces extreme exposure to both intense sunlight and freezing temperatures as the southern hemisphere unleashes a torrent of meteorological abuse. Making camp in a mountain river valley, he subsists on a diet of wild woodland salad, tadpoles and ant eggs before getting to grips with tickling trout in the fish-rich waters. In a final demonstration of thriving, he builds an automated fishing system and creates a living larder to keep his food source alive in preparation for a last evening mega-meal.
