When a skilled assassin (martial artist Rick Yune, who also penned the screenplay) declines an assignment to kill a pop star (Dania Ramirez) who's under the protection of his bodyguard half brother (Bokeem Woodbine), he invokes the ire of Bangkok's stealthiest professional killers. Now, the two siblings are literally fighting for their lives, armed only with their courage -- and the skills they learned from their father (Keith David).
