In each episode of the series, host Bear Grylls is airlifted into the wilderness with only a few tools to aid in his survival. The former British special forces soldier is typically depicted as subsisting for several days without intervention or interruption while cameramen follow him off-screen.
What really happened:Channel 4 confirmed that Grylls had stayed in sheltered accommodation on at least two occasions, even though his series had depicted him spending all his nights in the wild.
