火线狙击

肯尼迪总统的遇刺让身为他贴身保镖的弗兰克（克林特·伊斯特伍德 Clint Eastwood 饰）陷入了自责的情绪中不能自拔。即使多年过去，但只要一想到此时，弗兰克总觉得是自己的失职和大意造成了这一悲剧。某一日，一个神秘的电话引起了他的警觉。打电话的男人名叫米奇（约翰·马尔科维奇 John Malkovich 饰），他告诉弗兰克，自己准备暗杀现任总统，并邀请弗兰克玩一个所谓的“游戏”，这个游戏的成败将直接影响总统的命运。 　　往事重演，这一次，弗兰克决定无论如何都要保护总统的安全。这个米奇到底是谁？他这么做的目的何在？在一连串的疑问面前，一场激烈而又危险的追杀游戏逐渐展开。Frank Horrigan is a secret service agent who keeps thinking back to November 22, 1963, when, as a hand-picked agent by President Kennedy, he became one of the few agents to have lost a President to an assassin when Kennedy died. Now, former CIA assassin Mitch Leary is stalking the current President, who is running for re-election. Mitch has spent long hours studying Horrigan, and he taunts Horrigan, telling him of his plans to kill the President. Leary plans to kill the president because Leary feels betrayed by the government -- Leary was removed from the CIA, and the CIA is now trying to have him killed. After talking to Leary, Horrigan makes sure he is assigned to presidential protection duty, working with fellow secret service agent Lilly Raines. Horrigan has no intention of failing his President this time around, and he's more than willing to take a bullet. White House Chief of Staff Harry Sargent refuses to alter the President's itinerary, while Horrigan's boss, Secret Service Director Sam Campagna, is supportive of Horrigan. As the election gets closer, Horrigan begins to doubt his own abilities, especially when Horrigan's colleague Al D'Andrea is killed by Leary. But Horrigan may be the only one who can stop Leary.
