The War is just over. In Venice, a city elaborately and affectionately described, the American Colonel, Richard Cantrell, falls passionately in love with Renata, a young Italian countess who has 'a profile that could break your or anyone else's heart'. Cantrell is embittered, war-scarred and old enough to be Renata's father, but he is overwhelmed by the selflessness and freshness of the love she is offering.
