They finally meet each other; the adult siblings discover that they are as different as night and day. Chad has become a generally nice guy, while Alex sports leather duds, slicks his hair back and smokes cigars. But the brothers soon figure out that they have two things in common: martial arts, and a desire to take revenge of their parents' death. Hong Kong then becomes a battleground, with the brothers delivering kicks and punches as they combat Griffith and his henchmen. But will the twins end up fighting each other for the affections of Alex's girlfriend?
