This evening is the final episodes of series 4 as the remaining castaways battle to keep going.
Things got really grim last week when the worst storm the show has ever seen battered the island, forcing Bear's safety team to step in to keep the group alive.
Many wanted out of the show but they eventually agreed as a group to continue - but can they tough it out right to the end?
In tonight's show, 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 but it's Aran and Jacqui who hit the big time.
They stumble across a caiman crocodile - a vicious adversary, but rich in calories. Can they pass the ultimate test and provide food for all?
Straight after the final episode from The Island itself follows a special end of series recap.
Airing at 10PM, Surviving The Island sees Bear Grylls recapping the series, looking at how the two groups from two different generations lasted five weeks on an uninhabited Pacific island.
Marooned with only a handful of basic tools and the clothes on their back, the castaways had to endure extreme weather and stormy relations within the group.
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?
The Island with Bear Grylls airs at 9PM on Channel 4.
