Wes and Stee brave crocodile-filled waters to build a fish dam and get their first catch of the challenge. Teal and Waz use a mosquito net to catch six terrapins. A heat wave has two survivalists on the brink as medics assess if they can continue.
At the last water source, an abandoned cage may be the only viable shelter. Teal and Frank both score bow wins. A second crocodile has Wes on edge.
Days from the end, Teal's sudden tailspin threatens her challenge. Desperate for food, the remaining survivalists use scavenged wire to dredge the pond. With no rescue coming, they must escape the apocalyptic landscape to return to civilization.
