In 1938, the river city of Wuhan fell, and the Chinese nation fell into the heaviest darkness.
Shen Ye, a chemical engineer who returned from studying in Germany, served his country during the Wuhan Defense War. He was spotted by senior military officials and ordered to lurk, code-named "Yangtze River No. 1."
However, no one knows his real code name - "Steel Needle".
He is like a steel needle, forged by the Special Branch of the Communist Party of China. With the red faith of his father's generation, after breaking into the military command, he once again sneaked into the heart of the Japanese and puppets, walking on the abyss and on the tip of the knife.
He dealt with the cruel Japanese invaders, the cunning Wang puppet, the suspicious military commander and the staunch underground party. He faced three women with completely different identities and positions: one was a red beacon that illuminated his path of faith, one was a blue rose that attracted him fatally and fell in love with each other, and the other was a clear spring in troubled times that made him feel pity and guide his growth.
Every transmission of information is accompanied by a test of life and death; every change of identity is on the edge of exposure.
This is a story about disguise and loyalty, passion and faith. See how Shen Ye stirred up the storm with his triple identity. In the torrent of history, he grew from an upstart in the military to steel, and finally grew into a red ace that frightened the enemy!
