In 1937, Shanghai was undercurrent.
Chen Qingzhou traveled through the French Concession as a small patrol officer. At first, he was suspected of murder, but he unexpectedly awakened the daily intelligence system.
Three pieces of information every day.
One makes a fortune, one saves life, and one kills enemies.
From then on, he investigated cases during the day and lurked at night.
Handing out secret messages in the shadows of the dance hall, intercepting spies in the dark alleys of the concession, and overturning the situation step by step between gunpoint and lies.
The military commander suspected him, the special high school class wanted to kill him, the traitors wanted to bribe him, and the gangsters wanted to take advantage of him.
But they didn't know that the little policeman who seemed to be greedy for money, lustful and able to get both sides of things was the mysterious figure stirring up the spy sea in Shanghai.
Codename: Night Crow.
When he comes, the enemy cannot sleep peacefully.
