Treasure Island with Bear Grylls
The older group land well, finding a place to set up camp and starting a fire with ease. On the neighbouring island, the younger team are lost in the jungle and not doing so great.
The young group's campsite turns into a swamp in the rain. They join up with the olders, but immediately there's a row. Freddie kills a snake. And Kaggy goes on a wild turkey hunt.
With the old and young living side by side, the group hope to hit their stride. But hunger and frayed tempers lead to bust-ups as the islanders turn on one of their own.
The islanders face mother nature at her most violent with a hurricane brewing and the future of the community at risk. And Karen and Jane decide to launch a splinter group.
After four weeks on the island, the group have collectively lost almost 30 stone. Can Aran and Jacqui make a killing with a dangerous caiman crocodile and provide food for all?
Bear examines how the two groups from different generations survived their five weeks as castaways. Was it the wisdom of age or the energy of youth that proved most valuable?
