Celebrities attempt to master the vertigo-inducing art of highwire walking in aid of Stand Up to Cancer. Team leader Paddy McGuinness, soap star Beverley Callard, former footballer Anton Ferdinand, Pussycat Doll Kimberly Wyatt, Love Islander Chris Hughes, French football icon David Ginola, adventurer Charley Boorman, TikTok star GK Barry, comedian Fats Timbo and Olympic champion Victoria Pendleton attend training camp in the Austrian Alps. In preparation for their feat in London, they face the biggest test of their fear and endurance yet, by crossing a balance bridge suspended between two platforms 650ft in the air.

The team face the 400-foot Schlegeis Dam in Austria but with departures, tears and tantrums getting in their way they need to work as a team to pull focus and conquer their fears.

The celebrities head to the top of Penken Mountain in Austria, which is 5,500 feet above sea level, to work on their focus. At the edge of the cliff, Chris Hughes loses control of his fear and worries he can't complete the challenge.
