Meijun (Anita Mui), Qin Ge (Andy Lau), and Xiaocun (Kenny Bee) are city mercenaries. Meijun and Qin Ge were childhood sweethearts, and they were in love with each other. Xiaocun, who joined later, also loved Meijun, and Meijun was wavering between the two. Meijun carried out a mission and blinded Laoying. Before Laoying died, he asked his apprentice Yinhu (Aaron Kwok) to avenge him. Yinhu chased Meijun, and Xiaocun died to save Meijun. Before he died, he entrusted his sister Huixiang (Yip Wing-yee) to Qin Ge to take care of her, and one of Yinhu's eyes was also blinded by Meijun. In order not to implicate Qin Ge, Meijun fled alone. Qin Ge took Huixiang and looked for Meijun everywhere. Until one day, Meijun's sister Meihui (Anita Mui) deceived Qin Ge and said that Meijun had changed her name to Pet Lady and was competing for a husband. Qin Ge won over everyone, only to find out that Pet Lady (played by Carina Lau) was not Mei Jun, so he could only refuse to marry Pet Lady and leave alone. Later, he finally found Mei Jun's whereabouts, but at this time, Silver Fox came to hunt her down again. Mei Jun was poisoned by Silver Fox's "Angel of Terror" and would be poisoned within 24 hours. Only Pet Lady could cure this poison. Qin Ge could only hold Mei Jun and go back to find Pet Lady...
