The President of the United States will be arriving by train in the town of Suddenly where he plans to then be driven to a nearby lodge. The Sheriff, Tod Shaw, has everything under control and with the assistance of the State Police, has set up a reasonable security plan. Soon however, Shaw is taken prisoner by John Baron in the home of Pop Benson. Baron and his henchmen gained access to Benson's home by posing as FBI agents. The house provides perfect line of sight to the train station and Baron is there for only one reason: to assassinate the President. Baron has no political agenda and is simply a killer for hire but it's left to the Sheriff, Benson and Benson's daughter-in-law Ellen to stop him.
