1967. The brutal murder of a woman sends shockwaves through the city of Krakow. Young detective Andrzej quickly determines the case in question could be connected with the victim's espionage activity during World War II. Alina, the deceased woman's sole relative, is not much help. That is, until she finds one of her mother's letters, a list of names, as well a document in Hebrew script.

Andrzej and Alina then join forces to put the pieces of the puzzle together, and discover the love affair between Alina's Polish mother and her German suitor during a turbulent time in history in the process.

But how does all of this pertain to references to the "fat man"?

A riveting, high-octane thriller that confronts a complicated predicament head-on with unorthodox methods, yet without a moralizing undertone.
