Bear Grylls abandons ten celebrities on an uninhabited island in the pacific; marooned with just a handful of basic tools, they must survive entirely on their own wits.

Without fire, food or shelter, lashed by a succession of tropical storms, the celebs are a soaking, miserable mess; while RJ Mitte and Lucy Mecklenburgh are desperate to make fire, Ryan Thomas and Iwan Thomas decide to prioritize shelter.

After nearly three weeks on the island, the celebrities are still without shelter and ravaged by insect bites and lack of sleep; when the group starts to build a communal bed, former Pussy Cat Doll Melody Thorton decides she wants one of her own.

Only six celebrities remain on the island; a check-up by the doctor reveals that the celebrities are alarmingly under weight and could be at risk of organ failure.

After two weeks on the island, ravaged by hunger, mosquitos and sand flies, tensions are building in camp; musician Jordan Stephens in particular is attracting the ire of the other celebrities, who feel he's not pulling his weight.

Bear Grylls returns to find out how the ten celebs coped when pushed to the edge of existence and left to fend for themselves in the wild; four celebs crumbled and quit the island, leaving just six survivors to welcome Bear to their camp.
