Autumn, 1937. Against the Imperial Army's objections, Lt. Colonel Yuuki
establishes the spy training group "D-Agency." The army sends Liuetenant Sakuma to serve as their liason to D-Agency, and he watches the applicants easily coast through the brutal examination process. Not long after, Sakuma is ordered by Colonel Mutou to search the home of a suspected American spy, the Japanophile John Gordon. Disguised as military police, Sakuma leads D-Agency on their first mission.
What's so enjoyable about 
deceiving one another like that?
ما الممتع في خداع الآخرين هكذا؟
Und was ist daran spaßig,
die anderen derart zu hintergehen?
¿Cuál es la gracia de engañarse entre sí?
¿Cuál es la gracia de engañarse entre sí?
Qu’est-ce qui vous amuse
dans toutes ces tromperies ?
E che gusto ci sarebbe 
a ingannarsi l'un l'altro a quel modo?
Qual é a graça de ficar 
 enganando uns aos outros?!
