Old and young go head to head in the new series of Bear Grylls' survival epic. Which generation copes best marooned in the Pacific when pushed to the limits of human endurance?

With old and young now living side by side, the islanders are hoping to hit their stride. But the lack of food is an ever-pressing concern, and tempers are fraying. Jordan is feeling out of sorts and then has a fight with Richie. The group are furious when Phil uses some olive oil to boost the fire rather than for food. And soon there's another bust up, bringing relations to breaking point. Could a shocking vote see the islanders turn on one of their own?
