The Island with Bear Grylls: Season 4, Episode 6

4 - 6: Surviving the Island

Survival expert Bear Grylls looks at how two groups from two different generations lasted five weeks on an uninhabited Pacific island.

Bear returns to meet the castaways to find out first-hand how they did it. Was it the wisdom of age or the energy of youth that proved most valuable?
