Naked and Afraid XL

Twelve veteran survivalists attempt to survive 40 days and nights in the badlands of Colombia. Standing in their way are deadly predators, stifling heat and ... each other.

After a week of being dropped into the dangerous and desolate badlands of Colombia, dehydration forces one survivalist to tap out. Meanwhile, hunger, thirst and distrust threaten to wreak havoc on several more competitors.

The remaining survivalists struggle to adapt to their environment and each other. Some consider migrating to find new resources, while tension continues to rise in other camps and could lead to the second tap-out of the season.

The remaining survivalists make a desperate trek across the scorching savanna in search of food. If they can't find sustenance, they will be forced to tap out of the most difficult challenge of their lives.

The remaining survivalists cross the 21-day milestone and enter into uncharted waters. Scarce resources force them to search for Piranha Lake, where they fight for their lives against a 90-pound electric eel.

The dehydrated and protein-starved competitors converge on a dangerous lake and compete for scarce food and water resources. Tensions rise as one of the groups feels pressured to share their meat with the new, starving neighbors.

After 31 days in the Colombian jungle, the survivalists feel the pressure to get the nourishment they need to survive extraction. However, when one member doesn't play by the rules, the future of one group is threatened.

A duo decides to attempt their extraction alone, causing contention between the teams. Both groups begin their 10-mile journey to the extraction point and must navigate treacherous landscape to try and finish the challenge.

Twelve of the show's veterans put their lives on the line and begin their 40-day, 40-night challenge in the sun-scorched bush of South Africa during the middle of a drought and alongside the deadliest predators on the planet.

On the drought-stricken plains of South Africa, the remaining survivalists enter the second week of their 40-day challenge. A lack of water leads one group to venture off to find others, and another group goes hunting again.

Tick-bite fever threatens to take out some of the challengers early, and deadly leopards circle the camp after smelling food. As South Africa takes a toll on the survivalists, frustrations build and explosive confrontations arise.

As the survivalists approach the halfway point of their brutal challenge, starvation and sickness are worse than ever. They must come together to help one another, but the battle for alpha male could end up being their downfall.

The survivalists miss an opportunity to secure enough protein for the team, so two members go on a hunting expedition. A lion encounter and mounting frustrations fracture the partnership, and one refuses to return to the group.

The survivalists are plagued by extreme hunger and trust issues that put team morale at an all-time low. With the rest of the team showing signs of breaking apart, one member makes a fateful decision that could cost him his life.

Contaminated fruit from a single tree sets off a shocking chain of events over a 24-hour period. As panic and illness spread through the group, the chances of any of the survivalists making it to Day 40 become questionable.

The stakes are higher than ever as deadly predators begin closing in on the remaining survivalists. They must find energy from deep within to secure food and begin their long journey to the extraction point.

Meet the 12 Naked and Afraid XL challengers as they prepare to survive 40 days and 40 nights in the sun-scorched bush of South Africa with some of the most dangerous predators on the planet.

The 12 survivors share behind-the-scenes footage of their 40-day challenge in South Africa. Through new interviews and never-before-seen clips, they reveal a whole new side of the most difficult group survival challenge on Earth.
