Jack Hill's COFFY (1973) made Pam Grier a star and had a major influence on exploitation pictures of the time but who would have guessed that said influence would extend all the way to Hong Kong? This Sun Chung effort stars Chen Ping as Gao Wanfei, whose little sister, Wanjing, turns up unconscious after being injected with heroin at a party. Wanjing has suffered brain damage and Wanfei watches helplessly as the girl goes through hell during her withdrawal period. Although she receives sympathy from officer Deng Weipin (Yueh Hua), an old school chum known in his department as "Drug Smasher," Wanfei launches her own vigilante campaign targeting anyone connected with the drug world. Posing as a junkie interested in trading her body for a fix, Wanfei gains access to a drug laboratory operation and slaughters the men inside. Narcotics kingpin Wu (Wang Hsia, wildly over the top) decides to put Deng out of action by getting him in trouble with his superiors. When that fails to get him taken off of the streets, the cop is subjected to a severe beating. Wanfei witnesses the incident but is oblivious to the fact that her politician boyfriend (Antonio Ho Wing-on/Sze Wei) has deep ties with the syndicate and that his anti-drug crusade is just a charade for the public.

Sun's film sports superior action choreography (particularly the early sequence where Deng is ambushed), along with additional nudity and sex, and better production values (including some wonderfully garish bars and apartments). However, Chen lacks Pam Grier's screen dominating charisma, leaving the picture a bit empty at its core. That said, this remains solid, well-produced exploitation fare with some impressive locations that Jack Hill would no doubt have loved to have at his disposal. The supporting cast includes Chan Shen and Tin Ching (as an outrageously fey subordinate of Wu).

The transfer is up to the usual Celestial standards and, thankfully, avoids the blurriness plaguing some of the earlier discs. The 5.1 mix is coherent but hollow, overextended, and unnatural sounding. The standard Celestial extras are included: video promo spots, bios/filmographies, and two photo galleries.
