Thirty years ago, a man of Miao descent asked Tse Kong (Lau Siu-ming) to keep a statue called the "Old Cave" on his behalf, telling him that the statue can allow him to become wealthy. Tse Kong soon makes a fortune, and became a tycoon in Shanghai, dominating both the police and underworld. However, Tse becomes intoxicated with Gu poison. Tse's friend Hao Cheung-ching (Ho Pik-kin) unscrupulously informs the secret of the "Old Cave" to the Japanese. Tse's second son Seung-wai (Stephen Tung), who is slightly neurotic, falls in love with female spy Yip Ching-wah (Fu Yuk-lan). Although Seung-wai knows that Ching-wah is getting close to him to steal the "Old Cave", he does not debunk her. Tse's third son Seung-cho (Andy Lau) is confidant and stable. Although he is greatly trusted by his father, Seung-wai has no interest in taking over the family business. Seung-cho and Chin Pong (Ray Lui) are close friends, but they both fall in love with Cho's classmate Yan So-sam (Patrica Chong). Difficult to choose between friendship and love, the three of them fall into a tangled love triangle. At this time, Ching-wah mysteriously dies, while Wai disappears with the "Old Cave". The influence of the Tse family have since declined, with strange things occurring and disasters coming one after another. Whether all this is manipulated by a culprit or caused by an unknown divine force, it is all unknown.
