Plot

It follows adventure racers and survival experts as they endure more than 100 miles of inhospitable terrain with nothing but what they can carry to claim a $500,000 prize.

In the most harrowing outdoor adventure competition yet, nine teams of two must rely on a combination of endurance racing, survival skills, and intuition as they navigate 150 miles of New Zealand's deceptively beautiful and harshest terrain. The nine teams participating include mountain climbers, smoke jumpers, river guides, and recent divorcees among others. In each leg of the race, the last team to reach the finish line will be eliminated from the competition. From the depths of ancient caves to frigid alpine summits, every step and every calorie is hard-earned. However, strength and speed alone won't be enough to win the grand prize of $500,000. Rather, only those with the strongest will to survive will be able to claim this life-changing prize.
