In 1941, on the isolated island of Shanghai, No. 76 Demon Cave was filled with blood.
Le Min, on the surface, is a "dope" translator of the puppet government intelligence bureau, but in fact he is the "Nightingale", a top agent deployed by the military commander. He has only one mission: to dig out the Japanese hidden stakes code-named "Ghost" on No. 76, And intercept the "Sakura Project" that is enough to subvert the East China Anti-Japanese Front.
He wanted to keep a low profile, but was unexpectedly targeted by Long Qiao, the director of Operations Division 76.
This woman is ruthless and has superb marksmanship. She is the Wang Puppet's number one killer, and she is also a celebrity in the Japanese military's special high school. She looked at him with scrutiny, suspicion, and even a trace of unexplainable entanglement.
On the one hand, there is the layer-by-layer investigation of No. 76, On the other hand, the Japanese army is pressing forward step by step; on the other hand, there are the successive sacrifices of comrades, and on the other hand, "ghosts" are everywhere.
Lemin walks on the edge of a knife. Every translation may be exposed, and every look at each other hides murderous intent.
When the long gun was pointed at him, and when the truth of the "Sakura Project" surfaced, Lemin discovered that this most dangerous woman actually hid the same secret as him.
A double agent meets a female evil star. In the devil's cave, are they enemies or friends? Should they join forces to break the situation, or hunt each other?
Tonight, another light on No. 76 Went out.
