Yuen Biao is a former Hong Kong officer. He quit after an "accident" occured where he kills an innocent teenager. He felt guilty and decided to train with monks to feel better. After 5 years, he joins the force again after an encounter with the supernatural at a performance. He realizes that he has no other choice but to help out with his visions, which are very accurate. When Yuen Biao meets up with his former friend, who is Gigi's dad, he is offered to live in an apartment next to them. There he meets Moses Chan, the man who got kicked out of where Yuen Biao would be living. Little does Yuen Biao know is that Moses is actually an undercover officer who's spying on the triads. Yuen Biao gradually learns the truth about Moses and they become good friends. They tackle on many strange cases along with Yoyo Mung, who became a lawyer after being a head officer/investigator.
