The film follows Pete Garrison (played by Michael Douglas), a Secret Service agent assigned to protect the President of the United States. Garrison is highly respected and has a distinguished career, but his life takes a dramatic turn when he becomes embroiled in a conspiracy involving an assassination plot against the President.
As Garrison investigates the threat, he discovers that there is a mole within the Secret Service who is leaking information to the conspirators. Garrison’s former protégé, David Breckinridge (played by Kiefer Sutherland), is assigned to lead the investigation and is suspicious of Garrison’s involvement.
Meanwhile, Garrison is also dealing with personal issues, including an affair with the First Lady, Sarah Ballentine (played by Kim Basinger). Their affair complicates matters further, as Garrison becomes a prime suspect in the assassination plot due to his close proximity to the President and his relationship with the First Lady.

In a series of twists and turns, Garrison uncovers evidence that implicates someone close to the President in the conspiracy. As the tension mounts and the stakes escalate, Garrison must confront the truth and confront the traitor within the Secret Service.
In a climactic showdown, Garrison confronts the true mastermind behind the assassination plot and puts an end to their plans. With the threat neutralized and his name cleared, Garrison is hailed as a hero, and the President’s life is saved.
