It's February 1942 and the Americans have finally joined Britain and its allies. Meanwhile, twenty-three-year-old Francesca Fabrino, like thousands of other women, is doing her bit for the war effort in a factory in East London. But her thoughts are constantly occupied by her unrequited love for Charlie Brogan, who has recently married a woman of questionable reputation, before being shipped out to North Africa with the Eighth Army. When Francesca starts a new job as an Italian translator for the BBC Overseas Department, she meets handsome Count Leonardo D'Angelo. Just as Francesca has begun to put her hopeless love for Charlie to one side and embrace the affections of this charming and impressive man, Charlie returns from the front, his marriage in ruins and his heart burning for Francesca at last. Could she, a good Catholic girl, countenance an illicit affair with the man she has always longed for? Or should she choose a different, less dangerous path?
