The book follows a jazz bassist named Sidney "Sid" Griffiths and his bandmates, from the jazz scene in 1939 Berlin and Paris into the 1940s, when Griffiths and his friends attempt to flee the impending peril that looms over Germany. Racial hatred is in vogue, and a mixed-race German citizen (dubbed by the Nazis with the epithet "Rhineland Bastard") like Hiero Falk can be arrested and simply disappear, lost to history. Juxtaposed against this is another narrative, set in 1992. Sid and Chip re-unite and travel back to Berlin for the screening of the documentary about Hiero Falk, and in which both Sid and Chip appear. Watching their life on the big screen turns out to be somewhat different from what they expected, and the mysterious letter that Chip has received leads them to another journey, across countries, time, and their own emotions.
