Second In Command (2006)

In the film, Jean-Claude Van Damme plays an official who's just been appointed as "Second in Command" to the U.S. Ambassador at an American Embassy in a small, turbulent Eastern European nation. When local insurgents attempt a coup d'etat, the nation's President takes refuge inside the embassy. The embassy is then besieged by the well-armed insurgents. The U.S. Ambassador is killed in the ensuing action, and now it's up to Van Damme and the embassy's small detachment of U.S. Marines to fend off the attackers.
