Not only has she inherited her father's passion for art but Marina is gaining a reputation as an expert in her own right. However, Vittorio is keeping a deadly secret from her. He has been hiding a Jewish artist in their basement and one day she returns home to find her father has been brutally murdered by a German officer. Devastated, Marina flees to Florence to seek help from the man who owes Vittorio his life. Renowned American art expert Bernard Berenson offers Marina sanctuary in his beautiful villa outside Florence and puts her in charge of cataloguing his vast art library.
