one or two celebrities are given the task of organising a couple's wedding day. all they are given is a 60-second message from the couple, a tour of the couple's house and two sidekicks from either partner to help them with the process. they have a set budget to spend on everything (including the stag and hen nights) and only have three weeks to arrange the wedding. they are allowed no contact with the couple until a few days before the wedding and nothing is allowed to be revealed to the couple beforehand.
