Everything’s more fun when you do it with a friend, even when that thing is surviving in the wilderness with nothing more than a knife and flint. Bear Grylls takes us on his epic adventures of survival but this time he’s not alone. Along for each of his journeys is a celebrity who gets way outside of their comfort zone and who learns a few things in the process. From Marvel superheroes to Academy Award winners, we get to tag along and see how the stars handle the gritty real world. Luckily with Bear there, they’ll probably come out the other side okay, if with a bit thicker skin.
