The secret battle under the neon lights, the life and death situation on the piano keys.
In 1937, on the eve of the Songhu Battle, storms were about to come in Shanghai.
Su Wanqing, the top luthier of Bailmen, was dressed in a cheongsam and turned everyone upside down. No one knows that there is Morse code hidden in her piano sound, and every performance is a message transmission. She is the "nightingale" of the underground party, the more dangerous she is, the more she sings.
Li Zheng, deputy director of Agent 76 Headquarters, is frighteningly decisive in killing people. No one knew that he never pointed his gun at his real comrades. He is a lurking "lone wolf", walking alone in the darkness, waiting for the dawn.
When they met for the first time, he was ordered to track down the "Secret Code of Piano Sound", and her piano room was turned upside down. When they met for the second time, he ordered her arrest and released her at the last moment. The third time, the fourth time... Every time I get close is a test, every time I look at each other it's a game.
When he lets her go, she says he is a traitor; when he protects her, she says he is acting. It wasn't until the whip fell in the torture room and the bullet penetrated his chest that she knew - it turned out that his "cruelty" was to bury her deeper; his "killing" was to protect her.
Yamamoto Shizuka, the director of Japan's super high school, is as beautiful as a philanderer and as sweet as a snake. She loved Li Zheng so much that she would destroy him if she couldn't get him. She set up a dragnet to see him kill Su Wanqing with his own hands.
Under the neon lights of Paramount, in the torture chamber at No. 76, In the dark alleys of the French Concession - the love and hate of three people, the war between two countries, the tragedy of an era.
The worst of times is also the best of times. Some people die in the darkness, and some people are reborn before dawn.
"On the day of victory, I will wait for you in Yan'an."
"I will live to find you."
