The Peruvian Amazon's aggressive piranha, venomous fer de lance and even poisonous plants test 12 survivalists. XL rookies look to last 40 days while vets try to make 60 and become Legends. Four survivalists will be gone in the first four days.

Jeff struggles to keep down food; Trish and Amber hit a breaking point; Matt, Dan and Waz cross piranha-filled waters to score a big kill; EJ and Steven's new camp is stalked by a jaguar; a survivalist leaves the group to go solo.

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

Three elite survivalists join the challenge; Dan and Waz take on dangerous prey; Amber battles an aggressive caiman to feed her team; Steven's main source of food turns sour.

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.

With Amber gone, Trish and Jen must fend for themselves; Amber joins forces with Steven and EJ; a distant fishing hole means a punishing journey for a team's next meal; Dan and Waz make a high-risk choice.
