Lan Kou Fat (Chow Yun Fat), Traffic Light (Chen Baixiang) and Wu Zhun Shao (Eric Tsang) who work in the same car repair shop are colleagues and friends. They all disdain the stinginess and meanness of their boss Liu Dingjian (Feng Cuifan). Lan Kou Fat reluctantly broke up with his girlfriend (Zhang Min) because he could not stand her snobbish mother. Liu Dingjian suggested that the guys go to Penang with a cheap tour group, but they found out that the tour group was not what they said. But in Penang, Lan Kou Fat and others met Dong Dong (Maggie Cheung) who was shooting an advertisement there and his friend Wen Zi. Lan Kou Fat wanted to get closer to Dong Dong, so he pretended to be a rich man, and Dong Dong also deceived him by pretending to be a rich girl. When the two attended a dance, they offended Zhao Wanxian, a real rich man, who also fell in love with Dong Dong. In order to retaliate against Lan Kou Fat, Zhao revealed Lan Kou Fat's true identity to Dong Dong, and Dong Dong was very sad to face the deception. Dong Dong is preparing to attend Zhao Wanxian's dance party, but she and her friends are unaware that the despicable Zhao Wanxian has other intentions, so Lan Koufa and others go to rescue her.
