In war-torn France, Jo McMahon tends to six seriously wounded soldiers in a makeshift medical unit. There is a growing tenderness between her and one of her patients, a Scottish officer, but Jo’s heart is seared by the pain of all she has lost and seen. Nearing her breaking point, she fights to hold on to joyful memories of the past, to the times she shared with her best friend, Kay, whom she met in nursing school. At the same time, Kay is trapped in a squalid Japanese POW camp in Manila. She clings to memories of her happy days posted in Hawaii, and the handsome flyer who swept her off her feet in the weeks before Pearl Harbor. Surrounded by cruelty and death, Kay battles to maintain her sanity and save lives as best she can...and live to see her beloved friend, Jo, once more.
