It has fallen into the hands of nefarious arms dealer Arnold Gundars, who plans to sell it to a rogue terrorist with access to nuclear warheads. Kelly is asked to penetrate Arnold’s palatial headquarters in Budapest while there to fight in a special bout arranged by the arms dealer, an avid boxing fan. But Alex and Kelly’s newly forged friendship is put to the test when sudden disaster forces allies to become enemies, and the two men must race against time to prevent the Switchblade from embarking on its deadly mission.
