The onset of World War II forces a young British couple to navigate the collapse of European stability while stationed in Romania. Guy and Harriet Pringle arrive in Bucharest as the geopolitical landscape shifts toward total conflict. Harriet struggles to establish an identity within Guy's expansive social circle, which is populated by academics, diplomats, and refugees.

The narrative framework utilizes a third-person perspective to observe the disintegration of the Balkan states through the lens of the Pringles' marriage.
