Naked and Afraid XL All-Stars

Stalked by lions, hyenas and aggressive crocodiles, 13 all-star survivalists try to survive for 40 days in Africa's sun-scorched Selati Basin. Resources are scarce and when one group scavenges meat, hungry predators stalk their camp.

An attack by a venomous predator puts one of the survivalists at risk just three days into the challenge. With food scarce, the other competitors hunt warthogs and impalas but as they track their prey, the survivalists are also being stalked.

One survivalist takes a huge risk and enters a leopard kill zone to secure a big kill for his team. A massive storm unleashes torrential rains on each camp and the temperature plummets nearly 40 degrees.

Freezing rainstorms torture the remaining survivalists, risking severe hypothermia, and a successful hunt ends up backfiring and could cost two survivalists the challenge.

One camp throws themselves into the lion's den to hunt for big game, while the other camp bands together for a group hunt and ends up finding a dangerous and unexpected food source.

A devastating injury and a vicious storm that destroys the survivalists' food supply threatens to tear apart the newly merged camp.

XL All-Star Matt Wright seeks redemption as he takes on the brutal challenges of surviving Africa by himself. After more than 20 days alone, Matt begins a search for the other XL survivalists.

Risking retaliation from a dangerous nearby leopard, two survivalists scavenge the predator’s kill to provide food for the team. Matt Wright joins the other survivalists and immediately causes a confrontation within the group.

Survivalists embark on several dangerous hunts to secure protein and prepare for their arduous extraction on the horizon.

Brutal injuries and life-threatening illnesses end the 40-day challenge early for even the most elite survivalists. Through unseen footage and interviews, the survivalists offer insight and perspective on the most memorable moments when it all went wrong.

In an epic two-hour event, the weak, divided group gets a much-needed victory when the hunters score a kill. To finish the challenge, the survivalists must complete a brutal extraction across deadly killing fields of lions, crocodiles and leopards.

The survivalists come face to face for the first time since their 40-day challenge in Africa.
