In 1946, to prevent the Chinese civil war, Zhou Enlai who represented the Communists held a talk with the Chinese Nationalist Party, and George C. Marshall, who represented the Americans at Plum Village in Nanjing. A lost notebook stirred the already turbulent peace talk. The ripples alert the three sides and a battle of spy and anti-spy began. Many historical figures like Zhou Enlai, George Marshall, Chiang Kai-shek, Soong May-ling, He Yingqing, Chen Cheng, and Hu Zongnan are depicted in the movie. Other fictional persona such as the ace agent Xiong Huiquan, the female journalist, and a secret spy who belongs to the Confidential Bureau adds tension to the critical moment.

With a unique perspective of the accompanying cameraman of Premier Zhou Enlai, the film tactfully tells the story that Premier Zhou went to the old revolutionary base area of Hebei Province at the beginning of the 1960s when our country suffered from the Great Chinese Feminine. He made in-depth research in Boyan commune of Handan District, work closely with the masses, followed up a clue and seized the culprit in four days and nights.

The tale of one man who fought against the tyranny of a ruler and led his people in battle in the ultimate sacrifice for his country.

In 1973, Premier Zhou Enlai, diagnosed with bladder cancer, returned to Yan'an after a 26-year absence. The 13 years he spent in Yan'an vividly came back to him. This land had nurtured the Chinese revolution, the People's Liberation Army, and the first generation of CPC leaders, solidifying the Party's leading position. Premier Zhou reflected on the contributions of the Yan'an people to the revolution and worried about the continuing hardships they faced. He urged the local cadres and the "sent-down youth" to contribute to the development of this revolutionary sacred land. The cadres pledged their commitment, and the sent-down youth vowed to put down roots in the yellow earth. Everyone was filled with passion and determination to improve the lives of the Yan'an people. Moved by their enthusiasm and resolve, Premier Zhou, despite his illness (which prevented him from drinking alcohol) raised a toast with everyone, solidifying their shared vow.
