In 1941, in the city of Suzhou, Gu Yizhong, a son of a wealthy family, went to an appointment with joy and met Xiao Ruotong, an underground member of the Communist Party of China. Xiao Ruotong gave Gu Yizhong a pen engraved with the words "Gift to Gu Yizhong", which has a profound meaning. Gu Yizhong asked excitedly if this gift meant that Xiao Ruotong had accepted his heart. Xiao Ruotong smiled and said nothing, and the atmosphere was subtle.
As a talented architect, Gu Yizhong, although he was born into a wealthy family, he cared about the country and actively participated in the fight against Japan and national salvation. This time, the underground party planned an operation to rescue Nishi Taro of the Japanese Communist Party. Xiao Ruotong secretly handed over the weapons, while Gu Yizhong was selected as the action guide because of his professional map of Yiyuan. He fought side by side with Brother Six, the captain of the action team, to jointly carry out this arduous task. Task.
The action team sneaked into Yiyuan, led by Gu Yizhong, but unexpectedly fell into a trap carefully laid by Wang's puppet agent Zhou Zhifei. As their alertness grows, they realize they've been ambushed, but the window for escape quickly closes. After a fierce exchange of fire, all six members of the action team, except Gu Yizhong, died heroically. Their blood dyed every inch of Yiyuan red.
At the last moment of his life, Sixth Brother still had high hopes for Gu Yizhong. He endured the pain and whispered to Gu Yizhong to go to Liangyou Coffee Shop at eight o'clock in the evening to find the contact code-named "Eagle" and continue the unfinished business.
Unfortunately, Gu Yizhong was arrested and escorted to Suzhou Secret Service Station No. 90, which was the dark and terrifying lair of Wang's puppet spy. Zhou Zhifei conducted a brutal interrogation of Gu Yizhong in an attempt to pry out the identity of "Eagle" from him. In the face of torture, Gu Yizhong remained unyielding. He was full of doubts and firmly believed that there must be a spy in the team. While enduring both physical and mental torture, he accidentally exposed the pen presented by Xiao Ruotong, which attracted Zhou Zhifei's attention. Zhou Zhifei smiled slyly and threatened that if Gu Yizhong did not confess, his girlfriend - who was probably the escaped driver - would be brought to justice. Gu Yizhong glared, but in his heart he became more determined to keep the secret.
After the operation in Yiyuan, Xiao Ruotong hurried to the Midian joint, but was given a warning by the underground party and immediately evacuated. At the same time, Gu Huizhong was nervously sending reports. Hu Zhiping was alert to the enemy's presence and quickly directed Gu Huizhong to hide and detonate traps to block the enemy's pursuit.
Hu Zhiping and Gu Huizhong wanted to meet the eagle, but they were surprised to find that the traffic station had been destroyed. Since Gu Huizhong was pregnant with Liujia, Hu Zhiping suggested that she return home to take refuge, where her father Gu Xixing was guarding her and it was relatively safe. Gu Xixing, a legendary figure in the military circles, was born in the Baoding Military Academy. He once served as the major general and division commander of the Northern Expedition. Even Chiang Kai-shek respected him. Japanese Major Kondo Masao was rejected for repeated visits, which further showed his prestige.
Huang Xinzhai, deputy director of the Suzhou Secret Service Station, informed Kondo Masao that Gu Yizhong was arrested. Kondo brought Gu Yizhong's pen to coerce Gu Xixing into becoming the governor of Wu County, but Gu Xixing remained unmoved. After Kondo left, Gu Xixing refused to plead with Gao Guanwu, a high-ranking Wang puppet official. At the same time, Xiao Ruotong learned that Lieutenant General Gu Yi had been executed and rushed to Gu Yuan anxiously to seek help from Gu Xixing. The situation was critical.
