However, after the celebrations, the family is followed home by a Triad hit squad on orders from Griffith and crime lord Raymond Zhang (Philip Chan). A shootout ensues, in which Paul and his wife are killed by Moon (Bolo Yeung), Griffith's henchman. Chad is rescued by the family bodyguard, Frank Avery (Geoffrey Lewis), and raised abroad. Alex is dropped off on the doorstep of a Hong Kong orphanage.
In the present day, Chad (Jean-Claude Van Damme) and Frank are running a successful martial arts business in Los Angeles when Frank reveals a new "business" for the two of them in Hong Kong. Soon after arrival, they find Chad's long-lost twin brother Alex (Jean-Claude Van Damme) and Frank explains their shared past. It is revealed that Alex is immersed in the Hong Kong crime world ruled by Zhang, and has a girlfriend who works for Griffith’s company, Danielle Wilde (Alonna Shaw).
