The greedy billionaire Luo Yiwun (played by Wang Qing) is secretly plotting a murder, but someone secretly records evidence of it. A secret agent throws the tape containing the evidence into the car of journalist A Miao (played by Zheng Wenyue), but A Miao is completely unaware of it. To find his father's whereabouts, the young Luo Jianlang (played by Alan Tam) sneaks into Hong Kong, but due to his resemblance to Luo Yiwun's son, a misunderstanding occurs. Luo Yiwun captures Luo Jianlang and A Miao, among others, and holds them captive, demanding to know the whereabouts of the tape. Afterwards, the group manages to escape from Luo Yiwun's clutches through their wisdom and courage. It turns out that Luo Yiwun attempted to bribe a judge (played by Cao Dahua) with a large sum of money, but was rejected. Angered and humiliated, he devised a plan to eliminate the judge. Upon learning the truth, Luo Jianlang and the others realize that the judge is in danger and decide to rescue him.
