Wedding Belles, written by Irvine Welsh and Dean Cavanagh, tells the story of four late twenty-something lassies: Amanda, Kelly, Rhona and Shaz. Amanda is a successful business woman with her own beauty salon and is about to be married to her gorgeous airline pilot fiance, Joshua. Her agenda is simple; she wants her wedding to be the best Leith has ever seen. As the wedding draws nearer, the impending celebration turns into hysterical carnage, as it always seems to do for the girls struggling to get on with their lives. The gang have been together since childhood; they have parted, loved and caroused, HARD. They look back on their raving days with fondness, but now it's time to grow up. With the big day fast approaching, the gang of girls are thrown into turmoil with a series of hilarious, shocking and heartbreaking revelations.
