Johanna Lennox, a working-class Scottish nurse, and Ellie Winthrop, a Voluntary Aid Detachment recruit from a wealthy British family, are thrown together in a general hospital in France during World War I.  

When Johanna’s mother dies unexpectedly, Ellie is there to offer the comfort she desperately needs, and their feelings for each other grow into an attraction neither can deny. Johanna is convinced they can’t have a future together and throws herself into her work to escape her pain. She volunteers to serve closer to the front and almost loses her life before being sent home.

When Ellie refuses to give up hope and goes to find her, will Johanna be able to trust that a love born amidst the horrors of the Great War can survive in a post-war world?
