Spring 1937, Peking.
A 300-year-old theater building stands on the cliff of the times.
Shen Yanqiu returned from Paris just to pay off his father's debt and find his missing brother. But the moment she stepped into Guanghe Building, she realized that this place was more dangerous when opera was not being performed than when opera was being performed.
On the stage, Yan Ruoqing's sleeves were flying as she sang "Life is like a spring dream" and the audience applauded. In the audience, the applause of the Japanese soldiers was as neat as a machine. The secret room of Ma Hongyuan, the president of the Chamber of Commerce, was opened, and the puppet Manchukuo spies were mixed in among the tea and cigarettes. The only clue left by her comatose father is a code made up of opera excerpts.
He wanted Guanghe Building to be used as an intelligence station.
She wanted Guanghelou to survive this disaster.
And he - on the stage is the charming Concubine Yang, and off the stage is a bottomless mystery.
Three people and one theater.
Spring in Peiping has not yet ended, and blood has already been splattered on the stage.
This is not a drama, it is a spy war.
Everyone on stage is gambling with their lives.
