Sergeant Honma Eiji has been assigned to the Shanghai military police. 
Not long after assuming his new post, he is summoned by Captain Oikawa Masayuki. 
Oikawa orders Honma to conduct an internal investigation and uncover an enemy agent 
who's infiltrated their ranks. As he explains the mission, they hear an explosion...
He was pursuing the opium 
missing from the vault.

Er ermittelte, wohin das Opium
verschwunden war.
Iba tras el opio faltante de la bóveda.
Iba tras el opio desaparecido.

l'oppio sottratto dal deposito.
