From the deserts of North Africa, to the waters of Scotland, the Second World War touches the lives of two women from two very different worlds. In Alexandria, Fran finds her world turned upside down as Rommel's forces advance on the idyllic shores of Egypt. The life of luxury and stability that she is used to is taken away as she finds herself having to deal with loss, heartache and political uncertainty. Meanwhile, in the Firth of Clyde, Catriona struggles between her quiet rural life and her dreams of nursing injured servicemen on the front lines. As the war rages on, the two women's lives become intertwined - bringing love and friendship to both.
