It's the Outsiders first day in the wild. A sceptical David Mitchell oversees the chaos as the teams are set survival challenges and compete for badges.
David is equipped with a hosepipe as he tests out whether the shelters he's asked the comedians to build are waterproof or not, and he also challenges them to design a camp gadget.
Tempers flare as the comedians take pot shots at one another in a hunting challenge, but they come together to try and convert David Mitchell to their weirdly complimentary new religion.
It's the teams last day living together in the wild. There's all to play for as they go all out to impress a sceptical David Mitchell and prove they can survive post-apocalypse by making shoes from natural materials and herding animals.
