Sean and Laura are madly in love, have been engaged for seven years but can't save enough money for Laura's dream wedding. 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 Sean will organise the wedding alone. They will have no contact and Laura 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 Sean get the wedding dress on time? Will his family have to step in to save the day or will the boys' boozy nights out ruin everything? Can this man give this woman a day she will never forget?
