1941, Shanghai during the isolation period. The forces of all parties are intertwined, and the Wang Puppet Government's spy agency "No. 76" And the Japanese Special High School are engaged in a cruel secret war with the military command and the underground party.
**Shen Shimo**, the "Silver Fox" of the Shanghai District under the military command, uses his identity as the inspector of the French Concession Patrol Room as a cover. He is thoughtful and ruthless, but deep inside he hides a secret that can subvert his beliefs.
A top-secret list called "Burial Flowers" was leaked, which included military agents lurking behind enemy lines. Shen Shimo must find the mole within three days and transfer the list to the underground party liaison "Nightingale". At the same time, he must also deal with the pressing steps of ** Sasaki, the director of the Special Higher Education Course.
A gold-plated Browning pistol is a token of Shen Shimo's connection with "Nightingale" and a relic of his late wife.
