Paris, 1914. Lady Elspeth Douglas is visiting friends when the shadow of war falls across Europe. As her French fiancé races to rejoin his unit, she tries to reach England, only to be trapped on the French coast amid refugees and wounded men. Elspeth pitches in to help wounded soldiers, getting closer and closer to the Front, soon finding herself in danger as enemy shells fall. Captain Peter Gilchrist comes to her rescue, pulling her away from the battle and to safety. But before they can properly say goodbye, they are separated.

In London, Elspeth is haunted by all she's witnessed, and she can't forget the gallant man who saved her. Without her guardian's consent, she trains as a nurse. She's determined to return to France to do her part, and to find the man she has no right to love. Then everything goes wrong. In this world of uncertainty, can love survive, or will Elspeth's troubled heart become another casualty of this terrible war?
