Frank Sinatra stars as a disturbed ex-serviceman, hired to kill the President of the United States in Suddenly, named after the quiet California town where the action takes place. Sinatra leads the group of paid assassins that takes over a house in the small town where the President is expected to pass through on his way to Los Angeles. Suspenseful and thrilling, Suddenly features Sinatra in an utterly detestable role with a fine supporting cast as the family members who try to maintain peace during their home's invasion.
