Frank (Clint Eastwood) is a grizzled old Secret Service agent, his claim to fame/infamy was that he was present when JFK was shot. Frank discovers a plot to kill the current president who is seeking re-election. Nothing too unusual there but it soon transpires that this is not a normal threat to POTUS. Frank begins a cat and mouse chase with a mysterious and deadly foe called Leary (John Malkovich) who will stop at nothing to achieve his aims.
As the election campaign reaches it's final stages, Leary prepares to strike. Can Frank stop him and gain redemption (and get his leg-over with fellow agent Lilly (Rene Russo))?
Leary's plot is pretty intricate and maybe slightly far fetched (though his amazing abilities are later explained). Eastwood does a great turn as the veteran with plenty of past demons, Malkovich superbly dark and menacing.
