An unlikely alliance scores the challenge's first big-game kill; Suzänne risks her survival.

Pushing past day 50, the final six survivalists come together as one group but must scramble to expand their shelter; the Amazon unleashes a bee swarm and a torrential storm; a knife accident threatens a survivalist's challenge.

A newly-formed tribe quickly works together to stalk and kill a caiman; the pressure to trek forty miles to extraction pushes two teams to make risky migrations; a survivalist is on the brink when medics discover parasites in their digestive system.

Steven takes a huge risk when he raids a caiman nest for eggs; Dan and Waz join forces to snare the vultures circling their camp; Amber, Trish and Jen take on a huge project but tensions could tear them apart.

Twelve survivalists enter a punishing African location where tribes in the area live by a simple principle: banish the weak; as the 40-day challenge begins, deadly crocodiles and territorial leopards circle; a survivalist is targeted for banishment.

Scrambling from the start, 12 elite survivalists take on their harshest location yet, the sub-freezing Rocky Mountains of Montana.
