The general format of each episode is the premise that Grylls is left stranded in a region with his film crew. The episode documents his efforts to survive and find a way back to civilization, usually requiring an overnight shelter of some kind. Mostly there are wild terrains – jungles, forests or similar non-urban areas Grylls also tells about successful and failed survivals in the particular area which he is in. The show is how to deal if you fall into quick sand, if you get attacked by an alligator, if you have to make a raft. I get a really good briefing before we go. I know there’s a big river there, there’s gonna be a great cliff climb there, there’s loads of snakes in those rocks, watch out for an alligator
