High above the Mediterranean, on the French Riviera, stands a beautiful pink stucco villa. Once a playground for the rich and glamorous, now -- in the aftermath of World War I -- it is a convalescent home for sick and wounded nurses. Scottish Flora Garvie is here recovering from four traumatic years on the ambulance trains. And here she will meet again charismatic but troubled Kit Carlyle, a regimental chaplain who no longer believes in his calling and certainly doesn't believe himself worthy of Flora's love. Their dramatic rollercoaster of a story will take them through death, separation and war, until a terrifying game of cat and mouse in Occupied France seals their fate.
