In the waning days of World War II, Hana, a Canadian nurse, refuses to leave the temporary hospital in a Tuscan villa where she cares for her mysterious English patient, a soldier burned and bandaged beyond recognition. The patient is haunted by the memory of a love affair in North Africa. Hana is joined by Kip, a Sikh bomb-disposal expert, who becomes her lover, and by Caravaggio, a friend of her father and sometime-criminal-turned spy. The three establish a loose pattern of precarious existence in a ravaged world and form a bond of love around the dying man whose identity they try to uncover.
