The plot of the movie is smiple. It is about a unit of the CIB unit of the Hong Kong Police being assigned to keep surveillance on a company that the government is investigating. The movie did not spend enough time building the characters and background. There were moments of mission-impossible-esq scenes to create suspense but did not really carry through the movie. The several twists in the plot were too predictable and did not give the audience the feeling of originality.
