Naked and Afraid All-Stars from around the world - including Australia, Brazil, Mexico, and the United States - battle for national pride and the largest cash prize ever awarded.

Divided into seven pairs representing their homelands, survivalists' skills are tested by three brutal and unpredictable ecosystems in South Africa's Zululand. From a scorching savannah stalked by leopards and rhinos to a humid marshland ruled by hippos and crocodiles, and into the violent Indian Ocean teeming with Zambezi sharks, teams must battle both the brutal elements and one another.

Over the 40-day challenge, they're given no food, no water, and no clothes as their primitive bushcraft skills, resilience, and interpersonal relationships are pushed to the extreme.
