The film recounts a pivotal chapter in Chinese revolutionary history: the Zunyi Conference held from January 15 to 17, 1935, in Zunyi, Guizhou. During this meeting, the Chinese Communist Party corrected the military errors of Wang Ming’s “leftist” leadership and began establishing Mao Zedong’s Marxist line as the guiding force within the Party. This turning point helped save the Party, the Red Army, and the revolution itself. The film is structured into five key segments: The Great Retreat from the Soviet Base, The Bloody Battle at the Xiang River, Zunyi at Dawn, Crossing the Dadu River, and The Triumphant Meeting in Northern Shaanxi. In the dramatic Dadu River crossing scene, 17 Red Army soldiers brave the treacherous current, with two tragically falling into the river—highlighting the courage and sacrifice that defined this historic journey.
