Dodo Cheng plays Nan, a dedicated Mainland officer charged with providing security for a politician who is making a clandestine visit to Hong Kong.

Most of the running time is dominated by talk about the difference in culture between China, Hong Kong, and Taiwan. As a westerner, this sort of stuff went over my head for the most part and I became a bit bored by the proceedings. The fact that several bits are regurgitated from the previous movie doesn't help matters, either.
