Duodu Cai E (Liu Songren) was secretly plotting to overthrow the Yuan Shikai regime. In order to secretly return to Yunnan to start a rebellion, he used his close relationship with the famous courtesan Xiao Fengxian Zhang Fengyun (Zhou Haimei) to create a false impression of indulging in wine and women, neglecting state affairs. Yuan Shikai (Luo Le lin) did not believe that Cai E was truly decadent, and sent his chief of staff Mo Nitian (Lin Jiahua) multiple times to investigate the truth. He even lured Cai E's wife Bai Sit ing (Tian Ruoni) to Beijing, forcing Cai E to continue showing loyalty. For the bigger picture, Cai E used his feelings for Fengyun as a cover. However, Fengyun became deeply infatuated with Cai E, going so far as to renounce her profession to show her devotion, but unfortunately, Cai E remained cold towards her. This broke the heart of military officer Yu Ren guo (Ma Guoming), who hoped to take her away from this place of sorrow, but alas, Fengyun's love for Cai E was unwavering until death... Thus, one fought for revolution, and the other for love, caught in a seemingly ambiguous relationship filled with suspicion, torment, and longing, softly playing a touching and tragic love song.
