Inexperienced climbers Shirley Ballas, Ed Balls, Anita Rani, Dani Dyer, Alexander Armstrong, Dan Walker, Osi Umenyiora, Jade Thirlwall and Leigh-Anne Pinnock undertake an eight-day trek scaling Africa's highest mountain, Mount Kilimanjaro in Tanzania. Ten years since Gary Barlow, Alesha Dixon, Fearne Cotton, Cheryl, Kimberley Walsh, Ben Shephard, Ronan Keating, Denise Van Outen and Chris Moyles completed the challenge, the new recruits are taking on a tougher, longer route, and are likely to spend even more time at extreme altitude. Cameras follow their experiences.
