Chad (Jean-Claude Van Damme), a charming, smooth karate instructor from Los Angeles is mysteriously urged to fly to China by the man who raised him like a son, Frank Avery (Geoffrey Lewis, "High Plains Drifter," "Every Which Way But Loose"). There he meets Alex (Jean-Claude Van Damme), a streetwise gun-slinging smuggler raised on the back streets of Hong Kong. Chad and Alex discover they are twin brothers and were separated when their parents were brutally murdered twenty-five years ago.
