Diana, Marie and Jean are half-sisters who have found each other after a lifetime apart. Sharing a mother, all three of them were placed into care when young and grew up completely unaware of each other's existence. Jean and Marie were the first to discover each other, and then Diana found them. Diana and Jean have never met before, and now all three sisters are sitting down together for the very first time. We also meet classic car enthusiast Nick Morgan, who was adopted as a baby. It was only when he became a father himself that Nick felt an urge to try and find his biological family. Initial searches didn't yield any results, so Nick employed a genealogist. On the journey to discover more about the mother he never knew, Nick was delighted to find he had a sister, complete with family of her own. Now Nick is meeting Deborah's grown-up children Gemma and Daniel for the very first time.
