What happens when you put two complete strangers - sans clothes - in some of the most extreme environments on Earth? Each male-female duo is left with no food, no water, no clothes, and only one survival item each as they attempt to survive on their own.

A group of the best survival experts in the world take on an un-survivable situation: 40 days. 40 nights. No food, water or clothes. To survive they'll need to master the environment, pushing far beyond the breaking point. Will even one be able to finish?

For the first time ever, 12 Naked and Afraid All-Stars are going overboard. They've been told it's a Lost Coast challenge in the South Pacific, but they're about to be shipwrecked in the dark of night instead. The All-Stars will have to survive for 35 days -- and then rescue themselves to go home.
