Gemma is the maid of honour, but she's not here to throw confetti. After years of coming second to the bride, she's finally ready to stand up for herself. Leon is convinced his sister is making the biggest mistake of her life - their entire family hates the groom. He has to make her see sense before she says 'I do'. Francesca once spent a perfect night with the groom - right before he met the bride. If she doesn't tell him how she feels now, she never will. When a storm grounds their flight the night before the wedding, their plans collide. A few too many airport cocktails later, and their perfect schemes start to unravel - because the best-laid plans never go quite as expected, especially when love is involved.
