The Island with Bear Grylls: Season 4, Episode 5

4 - 5: Episode 5

After four weeks on the island, the group have collectively lost almost 30 stone and are increasingly beleaguered as they enter their last days as castaways. Karen is suffering more than the rest, with dangerously low blood sugar and diarrhoea. Bromance buddies Ben and Jager try fishing and then hunting for the island's elusive turkeys in the dense jungle. Aran and Jacqui stumble across a caiman crocodile - a vicious adversary, but rich in calories. Can they pass the ultimate test and provide food for all?
