Celebrity Island with Bear Grylls

Return of the survival challenge show in which 10 celebrities, including Sharon Davies and Ryan Thomas, are marooned on a deserted island with only basic resources.

Five days in, and still without fire, shelter or a proper meal, alpha males Ryan Thomas and Iwan Thomas decide to prioritise making a shelter - with disastrous consequences for the group.

After two weeks on the island, ravaged by hunger, mosquitoes and sand flies, tensions are building in the camp. Shazia Mirza goes fishing and Sharron Davies drops a bombshell.

The celebrities are still without shelter and ravaged by bites and lack of sleep. Former Pussycat Doll Melody Thornton wants her own bed and Ryan Thomas and Iwan Thomas go searching for food.

A medical check-up reveals the group are seriously underweight and could even be at risk of organisations failure. Iwan Thomas goes off on a secret night hunt to kill a caiman crocodile.

After marooning 10 celebrities on a remote Pacific island, Bear finds out how they coped, as the participants talk candidly about their tropical experience and how it changed them.
