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.
Japanese warriors don't go 
back on their word, right?
لا يتراجع المحاربون اليابانيّون

zu ihrem Wort, oder?
Los guerreros japoneses 
son hombres de palabra, ¿no?
Los guerreros japoneses sois 
hombres de palabra, ¿no?
Les soldats japonais
n’ont qu’une parole, non ?
E voi guerrieri giapponesi 
non vi rimangiate mai la parola data, vero?
Um guerreiro japonês nunca descumpre 
a sua palavra, não é mesmo?
