PLOT
Military Governor Choi Ngok (Damian Lau) has been attempting to overthrow the Yuen Sai Hoi government. To facilitate his plan to stage an uprising in Yunnan, he pretends to be fooling around with the highly sought-after courtesan Cheung Feng Wan (Chow Hoi Mei), nicknamed Siu Fung Sin, to avoid detection. Yuen Sai Hoi (Law Lok Lam), who is suspicious of Ngok, sends the Chief of Staff Mok Yik Tin (Lam Ka Wah) to spy on him. Later he even lures Ngok's wife Pak Sz Ting (Tin Yui Nei) to Beijing, hoping that this will force Ngok to pledge his loyalty to the government. To ensure the success of the revolutionary movement, Ngok carries on with his affair with Wan as a camouflage, without realizing that she has seriously fallen in love with him. Wan is ready to give up everything just to be with Ngok while he remains cold and distant towards her.
