Paddy McGuinness challenges a group of 12 strangers to make a gruelling trek across 18 miles of the South African wilderness - and resist a series of temptations along the way. The party starts out with a prize fund of £300,000 to be shared at the end of the journey, but each time one of them cracks, the money goes down.

Some of the trekkers are becoming more and more swayed towards alienating the rest of the group and splurging some of the prize money on home comforts. Can they resist sugary sweetness and an evening in a living room that reminds them of everything back home?
