This film is about cab driver Lung who is more than a little scarily obsessed with anchorperson Jenny Tung, played by Maggie Cheung. He feeds her stories that he witnesses while he's driving and they get to meet. He is infatuated with her, but is kind of rebuffed. A killer is loose, a vicious one, and you know they'll be involved somehow. Sandra Ng plays Ti, a fellow cabdriver. In one fun scene, she teaches him about a woman's erogenous zones to prepare for Lung's date with Jenny. She has her patently funny facial expressions and its fun to watch her, though you have the impression she also likes Lung. Nothing much to think about, just a cute horror/comedy film, more actually a drama than horror. Its always fun to see Sandra Ng and Maggie Cheung, so I recommend this film for that alone. Its worth your time.
