Nell is just eighteen when war breaks out, which means leaving her safe office job and starting to train as an auxiliary nurse. This brings her face to face with the grim realities of war, but she has a secret to comfort her: a soldier she's met and fallen in love with, who's promised to return to marry her. Then bombs fall on York, and for Nell, this coincides with a dreadful tragedy she can share with nobody. She must carry on, overcoming her hidden sorrow, but she never gives up hope that one day things will be right again.
