In that turbulent era of turbulence and war, China's mountains and rivers were shattered in 1935, and national peril hung on a thread.
Shen Yao, a brave and resolute female student, was born into a scholarly family. She was influenced by her patriotic father and has deep feelings for her country and nation. Wearing a blue student uniform and holding anti-Japanese leaflets, she shuttled through the streets of Shanghai, trying to arouse people's anti-Japanese enthusiasm. Once, she was almost hit by a Japanese military vehicle. At the critical moment, Lin Yu, a mysterious underground party member, stepped forward to save her. Lin Yu has a resolute face and deep eyes. He claims to be a reporter, but in fact he shoulders an important underground party mission.
From the moment they first met, their fates were closely intertwined. Their common patriotism allowed them to participate in anti-Japanese activities together, organizing street speeches to call on the people to unite to resist the invaders; they walked the streets to raise supplies for the anti-Japanese fighters, and never gave up in the face of rejection and cold looks. In the process, they gradually got to know each other. Shen Yao found that Lin Yu was brave, smart and responsible. Lin Yu was also attracted by Shen Yao's bravery and kindness, and the two fell in love. However, the road to love is not smooth sailing. They face pressure from all sides. Shen Yao's family opposes their being together because of Lin Yu's dangerous identity, and Lin Yu's underground party work also puts him in constant danger.
In 1937, when the Anti-Japanese War broke out, Lin Yu received an order from his superiors to go to the anti-Japanese base area to perform important tasks. The two were painfully separated on a cold night. Shen Yao began a long wait. She continued to participate in the anti-Japanese and national salvation movement, and encountered many difficulties and hardships in the difficult years.
