Luke and Gemma are madly in love, have been together for two years and can't wait to get married. But weddings don't come cheap and, with a six-month-old baby, they have other priorities. So, to speed things up, they are given 12,000 pounds towards their big day. But there is a catch. They have both agreed in the presence of a lawyer that Luke will organise the wedding alone. They will have no contact and Gemma won't know a single thing about her wedding until the big day three weeks later. Three weeks apart will push their relationship to the limit. Will Luke score an own goal, will he prove himself to be man or mouse, or will he trip up before he even gets to the altar? Can this man give this woman a day she will never forget?
