Eight contestants put their nerve, general knowledge and dignity to the test in Steve Jones' explosive Saturday night gameshow. There's a 10,000 pound prize for the winner, and every round sees one contestant leave the show by some of the most nerve-wracking, adrenaline-pumping means ever seen on TV. Assisting Steve on the incredible 101 tower, the venue for the quiz, is co-host Nemone. There's nothing funny about a heavyweight boxer punching one of the contestants right off the side of the Tower, or asking the contestants to sit astride enormous rockets with the words 'Kaboom' written down the side. Or is there?
