Private detective Meng Bo (Jackie Chan) and his dead partner's sister Hui Xiang (Joey Wong) have just finished discussing with newspaper tycoon Imamura how to find the whereabouts of his missing daughter, Qingzi (Kumiko Goto), when they see Qingzi and several skateboarders weaving in and out of the street. After a thorough pursuit, Qingzi disappears. Hui Xiang originally wanted to hold a birthday party for Meng Bo at Meng Bo's house, but she didn't want to open the door and find that seven beauties were already waiting. In anger, Hui Xiang threatened to take an advance honeymoon on the gambling boat "Fortune". Meng Bo rushed to the dock to explain to Hui Xiang, but he couldn't find her anywhere. At this time, the "Fortune" was about to set sail. Meng Bo mixed in with the tourists who came in one after another and got on the boat. Qingzi and Hong Kong police officer Yazi (Yau Shu-ching), who was dressed as a sexy girl, were also on the boat. Three women are a drama, not to mention the aggressive and lustful Meng Bo.
