The Sentinel, 2006 film starring Michael Douglas, Kiefer Sutherland and Kim Basinger. Good political based movie. Our hero (Douglas) is a secret service agent in the midst of an affair with the president’s wife (who he also protects). When a conspiracy to kill the president is discovered all agents must take a lie detector test to prove they are not involved and when our hero fails (because he was hiding his relationship) the department thinks he is behind to assassination conspiracy.
The hero must then set out to prove his innocence and find out who the real assassin is before it’s too late. Very good cast choice, the visuals were authentic looking and the story was solid all the way through. Would watch this one again some time.
