From the 1920's Republican era to the Sino-Japanese War, they struggled in an environment where unscrupulous merchants colluded with officials, warlords, Japanese spies, and bandits. Since the ancient times, Hongjiang has long been an important and prosperous commercial port for Xiangxi. It is rich in high-quality tung oil that's known as Hong You.

Yang Da Jiang, the eldest son of the Yang family, engages in activities for the Communist underground to raise funds for the revolution. The two daughters of the Liu family both fall in love with Yang Da Jiang and fight hard to secure Hongjiang City. Da Jiang's younger brother Yang Er Jiang joins the Kuomintang by accident.
