The Sentinel (2006)
Michael Douglas plays a senior member of the First Lady’s security detail, whose credibility is damaged when it is discovered he is having an affair with the First Lady. When a fellow security officer is murdered, fear spreads that a plot to kill the president is afoot and a mole in the security detail is helping to advance the assassination. Michael Douglas is doubly motivated to uncover the plot because he fears suspicions focused on him will take the heat off the real traitor.
It was an okay movie. There were some things that didn’t make sense but it mostly worked. There were some good twists and turns. They did a good job of making me feel as if I was really looking behind the scenes at White House security detail.
