During the Second World War, in 1943, Anne Frendo, a young dreamer and artist, living alone with her father in Tunisia, discovers, by chance, the lifeless body of a French soldier, parachuted in. At the invitation of her aunt, Sophie Frendo, an Egyptologist, she sets out on a journey that leads her to Sfax, Egypt, taking with her a letter that the soldier had begun to write, and which seems to be intended for her.
