In 1948, the fight between the Kuomintang and the Communist Party had reached the most critical moment. The political and economic system in the Kuomintang-controlled area was out of control, prices were soaring, corrupt officials were rampant, and the rule of the National Government had long been in jeopardy. At the same time, Meng Ao (played by Liu Ye), a colonel of the Jiangqiao Aviation School of the Kuomintang Air Force, was on trial for defying military orders. Fang was born in a wealthy family. He was the son of Fang Buting (played by Wang Qingxiang), the manager of the Peking Branch of the Central Bank, and the other identity was an underground member of our party lurking in the national army. After the intervention of Jiang Jingguo, Fang was exempted from punishment and transferred to the Preparatory Cadre Bureau of the Ministry of National Defense. Later, he participated in the "Peacock Flies Southeast" operation to investigate the fraud of the Peking Branch. In the turbulence of the times, there were suspicions and investigations from within the national army on the one hand, and plots and infighting from colleagues on the other hand, and there were more dangerous situations in the current war. Fang and all the underground workers have forged the cornerstone of the rise of New China with their red blood and loyalty... This film is adapted from Liu Heping's novel of the same name.
