It is 1936 in Berlin, Nazi Germany. A Japanese reporter named Sohei
Tohge is covering the Berlin Olympic Games for the Japanese press. As he
sits in the Japanese press box watching the many track and field events
of the day, he receives a call from his younger brother Isao, who has
been studying in Germany as an international student. The two make plans
to meet as Isao mentions he has something of importance to share with
his sibling. While Sohei initially thinks his little brother may have
found a young frau, Isao's tone is clearly that of one who is troubled
by topics much heavier than romance.
When Sohei arrives at Berlin University, he finds his brother's room has
been through some sort of violent ordeal. A mysterious message was left
on a note pad and a window was left wide open. And tangled in the
branches of a tree directly below Isao's window rested his dead body.
Isao was murdered.
Sohei would immediately launch an investigation to the murder, but
almost instantly all traces of information regarding his younger
brother's study in Germany has vanished. The police were of no help.
Isao's room was also cleared and rented out to another person. Even his
building manager feigned ignorance. It was as if he had never existed.
Investigating the matter, it is later learned that this murder is
connected to a document he mailed to Japan with information regarding
Adolf Hitler. As events progress, the lives of three Adolfs, each from
distinct origins, intertwine and become more and more tangled as Sohei
Toge searches for his brother's murderer.
