The Island USA with Bear Grylls
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 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.
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.
