London 1920: As the body of the Unknown Soldier makes its way home from the fields of Northern France, three women are dealing with loss in their own way: Hettie, who dances for sixpence a waltz at the Hammersmith Palais; Evelyn, who toils at a job in the pensions office, and Ada, a housewife who is beset by visions of her dead son. One day a young man comes to her door. He carries with him a wartime mystery that will bind these women together and will both mend and tear their hearts.
