After a sudden death, Luciana is obliged to carry out a final wish for her grandmother: to locate three women and return to them personal objects of great sentimental value (a wedding ring, a locket and an engagement ring.) Doing this means revisiting a past which isn't hers but will shape her present life and transform her future. With the help of her grandmother's diary and the investigations of a local researcher, Luciana meets the volunteers: four women who dared to defy fate, giving their lives to the service of others, as Red Cross nurses during the Second World War.
