Women in the Military Factory

In 1977, deep in the mountains of Suxi Town, Taihe, Jiangxi, the chimneys of the state-owned Qingjiang Chemical Plant (818 Factory) smoked day and night, and the roar of the nitrocellulose production line was the most profound youth background of a generation. Yu Anan, an ordinary craftsman in Factory 818, wears work clothes and has a pair of skillful hands, holding up half the sky in the flammable and explosive chemical workshop. She was deeply in love with Xu Jianguo, a student from Shanghai who aided in the construction of the country, but his mother firmly opposed it. A sudden accident completely shattered their first love. In order to fulfill his filial piety and responsibility, Xu Jianguo was forced to marry Xia Yu, whom he did not love, and then rushed to the border battlefield, with his life and death uncertain; Feng Tianfang, that taciturn local employee, has always been silently guarding Yu Anan, accompanying her through the pain of military transition, the factory's difficulties, and the haze of the "sacrifice" of her lover. From the emergency supply of nitrocellulose for military use to the difficult research and development of civilian filter membranes; from the laughter in the dormitory to the helpless end of the factory's bankruptcy; from the regretful miss of young love to the mutual affection of middle-aged people, every inch of the 818 factory is engraved with their youth, dedication and regret. The competition between Shanghai-aided lane girls and local girls, the counterattack of technical backbones in the workplace, the inability of ordinary people to cope with the tide of the times, and the love, hatred, and righteousness of family and country hidden in the mountains. When Xu Jianguo "resurrects from the dead" and when the factory faces bankruptcy, how should Yu Anan choose between Feng Tianfang's protection and the care of her first love? Where will the generation of 818 Factory go?
