Paul Hendy is challenged to persuade a certain amount of shoppers to do something. Fight their way out of a giant paper bag or finding a 5 note in three boxes of yukky stuff. A challenge that that takes several weeks to complete and is very difficult. These have included Climbing to the top of Mount Kilimanjaro in Africa or canoeing the Amazon. The main 'bit' of the show, as it were.
Someone writes in for themselves or is nominated.
Davina then turns up unannounced and asks them to pick one three envelopes, each with a different challenge inside given by a cryptic clue. They'll then travel to the place of the challenge which could be round the other side of the world. The show works rather well and doesn't pretend to intellectually demanding. It's action all the way and it works rather well. The one problem we would level at it is that it does seem to be too preoccupied with height.
