Audrey and Ian were best friends --- until they fell in love with the same man. To be precise, they fell in love with, married and divorced the same man. Twenty-odd years later, they’re right back at the beginning: Vienna, where their university study abroad turned into a love triangle from which they never quite recovered. But it’s Christmas, and Audrey’s daughter is getting married. Time to let bygones be bygones. Not for the sake of the holiday or even because they’ve matured with age…but because their mutual ex is nowhere to be found. It’s up to Audrey and Ian to track him down. As wedding plans go further awry, the former besties race to find the father of the bride.
