Based on the novel of the same name by Gerald Petievich, THE SENTINEL offers a rare look at the world of the Secret Service and questions what would happen if an insider were involved in a plot to kill the President of the United States. Agent Pete Garrison (Michael Douglas) has earned his stripes and is a fixture in the Secret Service.
In 1981, he took a bullet during the assassination attempt on President Reagan. More than twenty years later, he is an essential element in the first line of defense for current first lady Sarah Ballentine (Kim Basinger). But Garrison has some secrets that could end his career if they were discovered. When a plot to assassinate President John Ballentine (David Rasche) is suspected, Garrison finds himself the primary suspect.
Heading the investigation is Agent David Breckenridge (Kiefer Sutherland), who is convinced that Garrison--his former best friend and mentor--slept with his wife. With the help of rookie agent Jill Marin (Eva Longoria), who was trained by Garrison, Breckenridge is determined to crack the case and keep the president safe--even if it means taking Garrison down.
When accused of treason, Garrison leads Breckenridge and the other agents on a wild chase and the truth becomes more and more twisted. Is Garrison running in order to escape, or is he trying to prove his innocence while protecting his secrets?
Can Breckenridge put aside his old grudge and make decisions based strictly on the evidence presented?
Will Marin's allegiance remain with her new supervisor, or with Garrison, the field instructor who recommended her for her new assignment?
Most important, can the agents uncover the truth before more of their colleagues--and the president--die?
Directed by Clark Johnson (S.W.A.T.), who appears as Agent Charlie Merriweather, the film also features Martin Donovan, Ritchie Coster and Blair Brown.
