Second in Command (movie, 2006)

Armed insurgents attempt a coup d'etat in a troubled Eastern European country, and the president flees to the U.S. embassy for protection. When the U.S. ambassador is murdered by the ruthless and gun-happy rebels, it comes down to the second-in-command of the embassy, Sam Keenan, played by Belgian kickboxer Jean-Claude Van Damme, to use his amazing martial arts technique to defend the besieged.
