After a whirlwind romance, Josie and Harry are engaged to be married and she is putting every waking hour into planning the wedding down to the finest detail. This includes taking Harry, bridesmaid Diana and best man Ant down to her parents’ home in Cornwall for the weekend as that is where the wedding is going to be taking place. It should be a weekend of excited planning and preparations but, unfortunately, things don’t turn out entirely as Josie hopes. She turns into the 'bride from Hell' driving all her friends crazy with boredom as she talks non-stop about the wedding plans in the minutest of details. In order to liven things up, Harry and Ant persuade the girls to take part in a hypnosis experiment which will make them plight their troths to their true loves at midnight on Midsummer Night’s Eve. As you might imagine, all sorts of mayhem occurs as well as a few home truths shared.
