Bacteria brings a survivalist to their knees; a painful foot burn has a veteran struggling; conflicting survival priorities spark tension for Amber and Trish.

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.

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

Desperate for food ahead of their day 40 extraction, Jen pushes Trish to hunt new territory; Dan, Waz and Matt corner one of the Amazon's apex predators, a 6-foot caiman; when Trish and Amber's paths cross again, tensions resurface.
