Presenters Denise Van Outen and Fearne Cotton along with celebrity friends singers Alexandra Burke and Gabriella Cilmi and Total Wipeout presenter Amanda Byram undertake an arduous trek across the Peruvian Andes to raise awareness of breast cancer.
The celebrities are forced to give up their normal showbiz lives and deal with freezing cold temperatures, nights under canvas and altitude sickness. Joining the celebrities are six women who have all been diagnosed with breast cancer, some of whom are still receiving treatment.
