November 1920. Russia may have survived the Revolution, but a brutal civil war still rages. Families flee as the threat draws ever closer. However, as distant relatives of the Romanovs, the Kirilovs' heritage means they are never far from danger.

Struck by Lydia's plight, a benevolent diplomat brings her to England. Surrounded by luxury and endless opportunities, Lydia enjoys a life many would wish for. Yet, as uncertainty shrouds even her birth date, she accepts an invitation to visit Russia with a charming, but mysterious man. It is the perfect chance to discover the past she hardly remembers, but will Lydia truly find a home?
