During the Republic of China, war broke out everywhere, and Jiangcheng was in danger.
Su Qingheng, a female doctor who returned from Germany, abandoned the peace and stability of Peking and defended the battlefield for life and death, resisting the killings in troubled times with a kind heart. Lu Shougen, a soldier who was born as a farmer, grew from a lonely and exiled boy to an officer who defended Jiangcheng. He was a man of iron and blood, just to protect the land under his feet and the people in front of him.
When they first met, he was domineering and tough, she was cold and stubborn, and the doctors and soldiers had diametrically opposed positions. But being side by side under gunfire again and again, and waiting late at night again and again, made the two hearts slowly get closer in the turmoil. He doesn't understand Fengyue, but he will cook a bowl of hot porridge for her, plant a begonia, and clumsily carve out a lifelong promise; she is reserved and tenacious, but she is willing to put down her guard for him, teach him how to read, heal old wounds, and look for him thousands of times on the edge of life and death.
Love is deep in troubled times, and we can never help ourselves. The family and country come first, and the love between children comes behind. They love each other amidst suspicion and war, and stick to each other amidst separation and sacrifice. A deep-rooted love in the flames of war, a regretful parting in troubled times, and the most touching and sadistic two-way redemption under the righteousness of family and country.
