Only the bravest brides would let their groom organise the biggest day of their life, by himself. The grooms get £12,000 and the brides get no say in how it is spent. With a million ways to splash the cash and a million things to organise, can the guys pull it off in just three weeks? And will it be for better or worse? Bedfordshire couple Mercy (28) and James (31) have been together for 13 years and got engaged in 2009. But the stakes are high for James, as Mercy has been dreaming about her wedding since she was just three. So has he got any chance of delivering her perfect day with a Nigerian twist? Mercy comes from a Nigerian background, so it is a matter of family pride that James gets the traditions just right. How will this most laidback of grooms know what colour tribal outfits to buy? Can disorganised James prove his future wife wrong? Or will this nuptial novice's lack of planning undo his 'I Do'?
