Three loosely related stories about love, loneliness and desire, held together by one central event (a train accident) that sets these characters in motion. Andrew Lin Hoi is a mainland tour guide who’s stranded in China when the accident happens. He was supposed to pick up his visiting girlfriend Gigi Lai, but instead he gets stuck in a hotel where a Category 3 film is being filmed. There he strikes up a quick connection with the leading lady, who offers him a role in a graphic love scene with her. Meanwhile, Gigi has arrived in HK only to find herself alone with no one to turn to. Depressed and despondent, she takes comfort in the attentions of a lonely older man played by Patrick Tse Yin. The third and most interesting affair occurs between taxi driver Ben Ng and mainland hustler Wong Hei. The two hook up outside the train station and fight and fume in between steamy couplings.
