A serious leg injury puts Matt's challenge in jeopardy; during a dangerous white-water migration, the survivalists and their rafts are battered; tempers flare, and Gary squares off with Matt and Waz; new camp dynamics shake up the competition.

In the Australian Outback, 14 of "Naked and Afraid's" best, including Laura, Matt, Ky and Max, vie for the title.

Competitors battle for new resources in a grueling migration across punishing, elevated terrain; an injury puts Matt's challenge at risk; Waz unleashes a game-changing response to Jeff's cutthroat strategy; two survivalists exit the challenge.

Under the sweltering Outback sun, competitors scramble to build Aboriginal dome shelters and avoid elimination; medics race to give aid when Laura suffers whiplash, and Trish gets toxic sap in her eye; a survivalist must be evacuated via stretcher.

Starting with no tools, the survivalists scramble to prep for a brutal storm and two competitors are at risk immediately; a cutthroat survivalist puts the others on notice.
