Dan and Emily are crazy about each other. They live in a huge house in a beautiful location just outside Glasgow and want for nothing. All that’s missing is a baby - and they’ve been trying for years. Through a chance encounter they meet Kaya, an 18-year-old from the other side of the city, whose life is as precarious at theirs is comfortable. When Kaya agrees to carry their baby, it feels like they were meant to meet, but was it really by chance?
