简介
Returning to the series from last season is former U.S. Army Green Beret Weapons Sergeant Grady Powell, who tends to adopt a strong-willed and impetuous approach in order to overcome any obstacle. Grady is joined this season by new partner Josh James, an experienced outdoorsman from New Zealand's South Island. Josh and Grady must draw on their unique skills and experiences to battle with some of the toughest wilderness environments on the planet, where everything that can go wrong does, and opposing mindsets present frequent - and often amusing - conflicts.
