Larry Fishburne plays a cop who poses as a Hollywood drug dealer to infiltrate and destroy a cocaine cartel, but gradually discovers that the U.S. State Department has another agenda. Amply fulfilling the promise shown in A Rage in Harlem, director Bill Duke does a terrific job in spelling out the grim implications of this exceptionally violent 1992 picture, scripted by Henry Bean and Michael Tolkin (The Rapture). What emerges is a powerhouse thriller full of surprises, original touches, and rare political lucidity, including an impressive performance by Jeff Goldblum as a Jewish yuppie gangster. With Victoria Dillard, Charles Martin Smith, Sydney Lassick, Clarence Williams III, Gregory Sierra, and Roger Guenveur Smith. 92 min. (JR)
