Starting with no tools, the survivalists scramble to prep for a brutal storm and two competitors are at risk immediately

Twelve of the toughest and most experienced all-stars from "Naked and Afraid" take on South Africa's punishing Oribi Gorge in a completely new type of challenge.

Pushed to the brink, three competitors send shockwaves through the Outback. All camps are disbanded, and challenges going forward will be solo tests.

A primitive blade challenge on day one sends a pair of competitors home; survivalists are shocked to learn that sharing is not allowed in this competition; a race to retrieve bows cached in a 30-foot tree leads to a heated standoff.

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.

Shocking sabotage and a midnight medical emergency upend the competition. The elimination challenge requires a photo finish.
