In the autumn of 1947, in a class on the history of the Anti-Japanese War at the Southwest Associated University, lecturer Shen Nianyuan was reminded of the war years by an old photo. In the photo, young people who have returned from studying in Japan, air force pilots, and progressive students stand side by side. Their smiles hide their original aspirations and also bury the bifurcation of their destiny.
Shen Yanci went to Japan to study military affairs in the 1930s. After witnessing the atrocities of the Japanese army, he strengthened his belief in resisting Japan. He joined the party in 1935 and lurked under the warlords after returning to China. Su Qingyuan, a progressive student at Tianjin Normal University, took the lead in reading groups, printed and distributed anti-Japanese leaflets, and identified Shen Yanci as a "warlord eagle dog." A marriage contract that both parties hate bound the two people, but through repeated trials and side by side, they revealed each other's identities as Communist Party members - it turned out that they had already been on the same road.
During the war, Lin Changfeng, a good friend of the Air Force, flew a fighter plane to the air to help, fulfilling the promise of "the land and air work together to protect the mountains and rivers"; a classmate Zhao Wenxuan was greedy for life and feared death, and became the spy of the special high school course, exchanging former friendship for wealth. The copper plum blossom badge is a token of faith, the blood-stained poster is a witness to the battle, and the child "Nian Yuan" in troubled times is the softness and hope hidden in the hearts of the two.
From the secret communication in the streets of Jinmen, to the road protection operations at the railway hub, to the desperate defense at the mouth of the Sancha River, Shen Yanci and Su Qingyuan used their marriage as their shield and their faith as their blade to survive step by step amid the Japanese army's encirclement and suppression and the traitor's conspiracy. In the end, they detonated explosives with their lives and died together with the charging Japanese troops. Before their death, they still silently recited their children's names and vowed "Long Live the Communist Party."
