Chuang Tian (Yuen Wah) and Tung Siu Kuang (Cheung Kwok Keung) were famous demon hunters in the late Qing Dynasty, and they had a great reputation

However, during the late Qing Dynasty and early Republican period, when the society advocated the spirit of science, the art of demon hunter was criticized as being pedantic and nonsensical, and the duo was forced to migrate to Guangzhou, where Tian changed to be a policeman

But Kuang is obsessed with his past achievements and sticks to his profession, and tries to get close to a big businessman, Tong (Yam Sai Koon), who appears to be a legitimate businessman, but is in fact an unscrupulous one. After Kuang gains Tong's trust, he has a drastic change of heart, and is obsessed with money and conspires with Tong to use zombies to transport drugs.

When Tin learns of this, he is shocked, but he refuses to disclose it because of his brotherly love. After encountering Tong's daughter, Chui Ling (Tam Siu Wan), the disciple of Kuang, Siu Tung (Chen Xiaodong) is shocked by her and starts to pursue her passionately.

At this time, Kuang, in order to be with his deceased lover, Meng (Cao Zhong), forcibly took Ling's body to restore her soul, and Dong, in order to save Ling, went to ask for Tian's help, and Tian cast a spell to drive away Meng's soul and make her disappear forever.
