In Shanghai in 1930, Ruan Jingshu, the daughter of a textile tycoon, was forced to marry Cheng Yuanzhi, the son of a banker, in order to save the family from crisis. There is a hidden conspiracy behind the grand wedding - the husband has an affair with a singer, the Cheng family colludes with the Japanese to swallow up the national industry, and the childhood sweetheart Song Shuming suddenly returns with revolutionary ideals. When Ruan's father passed away and the dispute over the will triggered a family war, Jing Shu awakened from the flames of war and betrayal and turned the blood-stained textile factory into an anti-Japanese material production line, working together with Song Shuming to protect the last spark of national industry.
