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.
Once a spy is suspected, he's finished.
بمجرّد أن يتمّ الاشتباه بشخص 
.أنّه جاسوس، ينتهي أمره
Ist man erst der Spionage verdächtig,
ist man bereits erledigt.
Si sospechan que eres 
un espía, se acabó.
Si sospechan que eres un espía, se acabó.
Un espion suspecté de l’être
est déjà fichu.
Per una spia, il sospetto di essere stato scoperto
è già una condanna.
Um espião está acabado no exato 
 momento em que se torna suspeito.
