Wing Kwong Street in To Kwa Wan was included in the scope of reconstruction by the Community Improvement Bureau and the demolition works will start soon. The "Kowloon Emperor" Ah Choi is aware that an evil spirit, “Guangde Princess” was being trapped under the ground in that area 400 years ago. She was murdered by the ancestor of Ah Choi during the post-war period and she is ready to take her revenge. Ah Choi warned the Community Improvement Officer, Ah Yat that he must assist him to destroy the evil spirit otherwise Ah Yat will face his tragic deadly ending. After experiencing continuous miserable accidents, Ah Yat was left with no choice but to begin his journey of hunting evil spirit with Ah Choi.
