Former JLS star Aston Merrygold, MIC's Ollie Locke, comedians Dom Joly and Josie Long, The Hotel's Mark Jenkins, rugby ace and model Thom Evans, Embarrassing Bodies' Dr Dawn Harper, former Labour councillor Karen Danczuk, TOWIE star Lydia Bright, and former Blue Peter presenter Zoe Salmon are all giving up their celeb lifestyle for two weeks to see if they can hack it.
Left alone with just the clothes on their back and a handful of basic tools, they must survive entirely on their own wits. As things kick off, Ollie attempts to lead the group to a safe place to sleep, but it's Dom Joly who's voted El Presidente.
As the stars face three days without food and dwindling water supplies, can they stay the course?
