Cha Chuen-yee (LEGAL INNOCENCE) helmed this routinely plotted, but moderately enjoyable entry in the series. A criminal organization, operating out of South Korea, is selling stolen American military secrets to the Russians. Innocent Marine David Ng (David Wu Tai-wai) is framed for the actions of his (now) dead buddy (Vincent Lyn), who was a member of the gang and under investigation by the C.I.A. David manages to escape from his captors and, after initially refusing it, enlists the aid of Madam Yang (Cynthia Yang Li-ching) to prove his innocence. The key to his case is teenager May (Alvina Kong Yan-yin), the only witness who can speak on David's behalf. The climax takes place in Korea, as our heroes confront the villains on their home turf.
There is as much action as one would expect but it is not always as well choreographed as in previous entries (though Yang and Australian martial artist Kim Maree Penn have a terrific fight during the climax and Yang hangs from the side of a very tall building in a stunt that appears to have been staged with no safety rigging). Taiwanese actor David Wu is a lacklustre leading man and comedienne Alvina Kong is wasted as the secondary female lead, a part that gives her little of interest to do and no real opportunities for humor. The supporting players include Chris Lee Kin-sang, Billy Chow Bei-lee, Lo Lieh, Lau Kong, John Ladalski, Mark King, Steve Tartaglia, and Bruce Fontaine (who would later choreograph stunts on a number of major Hollywood productions).
