Bucharest, before and during World War II, where Bernard Davidescou lives with his parents and his older brother on Triumph Street, in the middle of a courtyard block inhabited by a dozen Jewish families and two Christian ones. When Romania, under General Ion Antonescus dictatorship, allies itself with Hitler and invades the USSR, the Jews in Bucharest face the threat of being sent to the Nazi extermination camps, after having survived the terror of the fascist Iron Guard. However, each Sunday morning, young Bernard, age twelve, passionate about politics and history, amazes the adults in the courtyard, Jews and Christians alike, with his analysis of the political situation in Romania and the development of the war on all fronts. Rue du Triomphe is the story of this young boy and his dreams and torments during this dark period of human history, while also chronicling a family in crisis, the discovery of sexuality and first loves, and the distraction offered by the cinema, religious searching and idealistic aspirations for a better world.

At the age of 86, Dov Hoenig decided to travel back in his mind to WWII Bucharest to tell the story of his 12-year-old self and so many Jewish families caught in the midst of struggle and terror.
