Danny Lee is a cop (in one of his better roles) who finally captures Panther, a drug dealer, after 3 years with the help of his undercover assistant, Anthony Wong. When Panther realizes that AW has betrayed him he swears revenge. Now one of the rules of HK movies is that when a triad member swears revenge, they are not kidding and the best thing to do is disappear immediately or at least get some police protection. Wong does neither and in an incredibly harrowing stomach wrenching scene he & his family pay for this miscalculation (one of the evil assassins is the Filipina Agnes Aurelio).
The case falls apart and the dealer is freed.
Lee and a friend of AW (Wong Jing again) decide to get their own version
of revenge. But instead of the usual bloodbath, they do it with a sting
that makes the movie quite different and enjoyable. There were just a few
silly attempts at humor by Wong Jing’s character that were irritatingly
out of place for a movie that could be so intense one moment and then slapsticky
the next. Joey Wong also stars as the rich girl that Lee uses in the plot
to get Panther.
