In Shanghai in 1925, Shen Ruohan, a young girl who returned from studying abroad, took over the textile factory left by her father, but faced suppression from foreign capital and blackmail from domestic warlords. She met Gu Tingchen, the warlord's adjutant who came to "discuss cooperation". Gu Tingchen secretly helped her fight against oppression, and the two fell in love with each other while saving the country through industry.
