The Blue Harvest, a military train developed by NATO, has been hijacked by terrorists--representatives of "The Knights of the Apocalypse". They issue their demands: a guarantee of safe passage for the train to the French border, and a ransom of 20 billion dollars. In return, they will release the French ambassador and his family alive.Military bodyguard Jack Morton, having narrowly escaped death in the terrorist attack, manages to sneak inside the Blue Harvest, in a solo bid to take back control of the train. He quickly discovers that he is the sole surviving member of the NATO team. It's up to him to save the French president and his family, and avert an international disaster of nuclear proportions. Will Jack Morton be able to rescue the hostages? Can he save Europe from a nuclear crisis?
