Jean-Claude Van Damme proves that two cracked heads are better than one in Double Impact. Van Damme plays twins Chad and Alex, who were separated at birth when their parents were brutally murdered by members of a Hong Kong criminal cartel. Incredibly both Chad and Alex have grown up to become world-class martial arts experts. Chad is a snobbish Californian karate instructor, while Alex is a cigar-smoking smuggler in Hong Kong. The two are brought back together by the family bodyguard Frank Avery (Geoffrey Lewis) to team up to avenge their parents' murder. But stacked against them is a thoroughly nasty, over-the-top assassin named Moon (martial arts film great Bolo Yeung).
