The Peacekeeper (1997)

This well-wrought Canadian direct-to-video actioner (in large part a knock-off of the Die Hard series) stars Dolph Lundgren as a maverick American Air Force pilot who during a flight disobeys orders and drops a large shipment of food for a starving group of Middle Eastern refugees. Too embarrassed by the publicity to discipline him formally, the Air Force gives him a new assignment: he is to carry the President's black bag, a special briefcase loaded with a computer that the Executive in Chief can use to launch a nuclear war. Following a press conference, the former pilot and the president (Roy Scheider) return to their hotel. Later, the floor on which they stay is overrun by terrorists who want to use the black bag to launch an attack on Washington D.C. During the scuffle, the pilot manages to escape, but not before the bag is grabbed by the terrorists. Later the hostage takers demand that the President commit suicide on television. If he refuses, then they will blow up the capitol city. Assisted by the only other man to survive the terrorist's initial attack, the pilot must somehow stop them.
