"Suddenly" is a small town in Southern California where nothing ever happens until word reaches the local police station that the train carrying the President of the United States will be making a brief stop at the railroad station during his current re-election campaign tour.
Security is tight as FBI agents descend on the area to see that every precaution is taken to ensure the President's protection. A car draws up at the home of a family whose house overlooks the station at the very point where the President's train will stop. A trio of men headed by John Baron (Frank Sinatra) announce themselves as FBI security men and enter the house. It is only when the genuine FBI agents turn up and are killed by Baron that the family realise he is a paid assassin intent on killing the President. He and his henchmen hold the family hostage at gunpoint as they await the arrival of the presidential train.
As the hours pass, Baron's pathological personality becomes more pronounced while the family try various ways to outwit him and his men - but to no avail. The killer's plans have been carefully laid and as the train approaches the tension mounts and it seems that nothing can prevent the death of the nation's President.
