Two pairs of complete strangers are stripped bare of all clothes and possessions to race across the English countryside in a bid to be the first to reach a cash prize for charity and their clothes.
Will they have the strength, resilience and resourcefulness to survive in the country's most extreme environments, with nothing but their wits? And as they move towards the finish line in a busy town centre, will they be able to improvise cover for their modesty in order not to alarm the locals?
Airs Wednesday 6th October at 9pm on E4.
