The work explores the themes of nationality, ethnicity, racism, and war, and includes elements of coming of age, spy fiction, and historical drama.

Upon arriving, he finds that his younger brother, who has been studying in Germany as an international student, has been murdered and had connections with Communist organisations.

Investigating the matter, he later learns that his brother's murder is connected to documents he mailed to Japan with information regarding Adolf Hitler.

While at the Hitler Youth academy, Kaufmann witnesses Kamil's father brought to execution after he comes to Europe to try to bring Jews to Japan through Shanghai.

After being tortured by the Gestapo, Toge eventually tracks down his brother's girlfriend, who is revealed to be a spy working for her father, inspector Lampe.

In Japan, Toge quickly becomes a target for both the Kenpeitai and the German secret police, who routinely chase him down and beat him in an attempt to find the documents.

During one of these pursuits, he makes friends with a Japanese police chief, who accompanies him on a chase to an island where Ogi is keeping the documents.

In the fallout of the July 20 Plot and Germany on the brink of military defeat under an increasingly unstable Fuhrer, he is sent to Japan by a surviving Lampe to complete his father Wolfgang's mission.

During his alienation of his family and friends in Japan, he is disowned by Yukie, who shortly thereafter suffers brain damage during the Allied air raid of Kobe.

Kaufmann's continued investigation eventually leads to the buried documents, which he discovers only after Hitler's death renders his entire mission pointless.

Kaufmann, who has joined the Lebanese PLO after being constantly chased down by Israeli Nazi hunters, arrives home one day to see his Muslim wife and daughter murdered by Kamil's division.
