It is the boldest test of endurance experiment ever attempted. 10 people will enter the wilderness carrying only what they can fit in a small backpack. They will be alone in harsh, unforgiving terrain with a single mission - stay alive as long as they can. These participants will hunt, build shelters and fend off predators. They will face extreme isolation and psychological distress as they plunge into the unknown and document the experience themselves. No camera crew. No producers. At stake is a $500,000 for whoever lasts the longest. It is the ultimate test of a person's will.
