Celebrity Island with Bear Grylls 2016 kicks off tonight on Channel 4 and there's trouble from the off.
As part of this year's Stand Up To Cancer campaign, Bear Grylls leaves 10 celebrities on an uninhabited island in the Pacific in a first ever Celebrity special of The Island.
Just like the main show, the group are alone with the clothes they have on a set of basic tools such as knifes.
Before leaving, they took part in a two day 'survival school' where the celebs learned about making fire, shelter, finding food and dealing with dangerous animals.
But now they're on their own.
In tonight's opening episode the group are dropped off by Bear in the water and told to swim ashore.
Once on dry land, setting up camp is the first objective with `Made In Chelsea's Ollie Locke leading the group into the jungle to find a place to sleep, while comedian Dom Joly finds himself voted into the role of 'El Presidente'.
The next day and in need of fresh drinking water, JLS' Aston Merrygold and former Labour councillor and 'selfie Queen' Karen Danczuk lead an expedition that ends with a distress calling being made.
Aston says: "There is no way I am risking my life for this s***" as he sends out an SOS for help.
Meanwhile, with the lack of water, Ollie reflects: “It is the closest I have come to thinking: ‘This is it – we might as well hold hands and close our eyes’.”
Following three days without food, Dr Dawn Harper from Embarrassing Bodies is seriously worried about the group's wellbeing. For one celebrity, the experience is too much to bear.
Celebrity Island with Bear Grylls starts tonight at 9PM on Channel 4.
