Naked and Afraid veterans take on the most intense challenge yet - surviving 21 days completely and utterly alone. While each survivalist returns to the challenge for a different reason - some to avenge a past performance, others to honor loved ones - all share the same will to overcome their fear of failure, outlast this ultimate test of survival and prove they can do it all without help from anyone else.

In complete darkness, inspired by extreme training scenarios of the U.S. military, Department of Defense and NASA, three strangers push themselves to the limit.
