While out on a job, burglar Luther Whitney (Clint Eastwood) sees a woman being murdered by her lover, who just happens to be the President of the United States. When the President’s aide and Secret Service bodyguards realize that their attempt to cover up the crime has an eyewitness-shaped hole in it, they (naturally) try to eliminate him. Predictable and implausible in roughly equal measure.
BTW – The book is better, they messed around with the plot to give Clint a bigger role.
