Jeff is called out for his "no hand-outs" survival strategy but refuses to back down. Through a free-wheeling discussion, new interviews, and never-before-seen footage, it's a new look into how the survivalists survived land, sea and each other.
The 10 remaining survivalists cross the 21-Day milestone and enter into unchartered waters. Scarce resources send the survivalists on a collision course. They fight for their lives with a huge electric eel and are visited in the night by a gigantic puma.
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.
Medics closely monitor Jeff's high fever and prepare his evacuation. The others prepare for an 5-mile extraction journey through the jungle and shark-infested waters. A survivalist pushes too hard leading to a medical emergency on the open sea.
After nearly three weeks in the bush, two survivalists have tapped out and most others are making desperate treks across the savannah in search of food. If they can't find sustenance, they'll be forced out of the most difficult challenge of their lives.
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.
The group is devastated when two critical survivalists leave the challenge. With just 10 days left before extraction, Jeff is forced to change his survival strategy but a medical emergency quickly has him on the brink of a tap out.
