We open on a park scene covered in fog, and we cut to a cityscape of London shrouded in fog. We then see a series of vignettes each depicting different election issues all clouded by fog - a suburban residential street with 'for sale' signs, a commercial street with a police car approaching the camera, an elderly woman straining to put a bottle in a bottle bank, a group of school children in a classroom, an operating theatre, a stock exchange and a soldiers packing in a barracks.The pace of the piece then changes gear as we see a massive fan start up in the stock exchange forcing the scene to become clear of fog, with the same effect happening in all the previous vignettes as you see a title, 'need some clarity on election issues?', 'BBC Making it clear.'
