12 Naked and Afraid veterans begin their 40 day and 40 night challenge in the sun-scorched bush of South Africa during the middle of a drought and alongside deadly predators.

On the drought-stricken plains of South Africa, a lack of water leads one group to venture off to find others and another group goes hunting for big game.

Only two weeks in and South Africa is already taking a huge toll on our survivalists, mentally and physically. Frustrations between survivalists explode, deadly leopards circle, and cases of tick-bite fever threaten to take some out of the challenge.

The Survivalists approach the halfway point of their brutal challenge. With starvation & sickness worse than ever they must come together to help one another, but the battle for Alpha Male distracts them from their strategy and may be their downfall.

Steven fails to return with Darrin from their two-day hunting expedition, leaving the group with no choice but to break camp in a desperate search for answers.

Ryan encounters a wild animal while he's defenseless and without the help of the group.

In a 24-hour period, the contaminated fruit of a single tree sets off a shocking chain of events. As panic and illness spread through the group it's questionable whether anyone will make it to Day 40.

As deadly predators begin to close in on the remaining survivalists, they must find the energy to secure food and start their long journey to extraction.
