After the chivalrous woman Qiu Moyan (Lin Qingxia), the chivalrous man He Hu and others risked their lives to rescue the descendants of Zhongliang, they fled to the Longmen Inn in the desert at the border and met with Zhou Huaian (Tony Leung), a subordinate of Yang Yuxuan. The Longmen Inn is actually a black shop. The proprietress Jin Xiangyu (Maggie Cheung) took advantage of the troubled times and used her beauty and coquettishness as bait to kill people and rob goods to accumulate money, but she fell in love with the handsome Zhou Huaian. In order to find out the secret passage out of the Longmen Inn, Zhou Huaian took advantage of the trick and agreed to marry Jin Xiangyu. On the wedding night, Zhou Huaian and Jin Xiangyu upstairs each had their own thoughts and secretly competed with each other.
