Despite its wartime time and the complexities of wartime spying and resistance and the very real and sometimes unreal presence of the Nazis, the set-up of this wartime noir is classicly typical of the style - - a man and a woman, both of whom are fleeing from their pasts, accidentally meet and he falls for her - - big time.
A chance meeting, indicative of the noirish fate of many a wartime film noir protagonist. He in particular feels that the past can never harm them, and urges his new love to forget it.
