In May 1950, Britain is struggling with the hardships of rationing and the aftermath of the SecondWorldWar. Peter Schormann, a German ex-prisoner of war, has left his home country to be with Mary Howarth, matron of a small hospital in Wales. The two met when Mary was a nurse at the POW camp hospital. They intend to marry, but the memory of Frank Shuttleworth, an ex-boyfriend of Mary's, continues to haunt them and there are many obstacles in the way of their happiness, not the least of which is Mary's troubled family. When tragedy strikes, Mary hopes it will unite her siblings, but it is only when a child disappears that the whole family pulls together to save one of their own from a common enemy.
