无懈可击

迈克尔·法拉第（杰夫·布里吉斯 Jeff Bridges 饰）是一名乔治华盛顿大学的历史系教授，单独抚养着9岁的儿子，他的妻子原是FBI探员，前不久死于一次执勤。最近，迈克尔家街对面搬来了一户新人家，奥利弗（蒂姆·罗宾斯 Tim Robbins 饰）和雪柔（琼·库萨克 Joan Cusack 饰）以及他们的儿子布雷迪。然而不知是由于正在讲授恐怖组织一课的职业惯性还是第六感作祟，迈克尔总是对这户新邻居心存怀疑，当然，周围没有一个人相信他的荒谬推理。迈克尔开始对奥利弗一家明察暗访，渐渐发现了原来奥利弗一直在用假身份生活，家族史也颇有疑点，但是奥利弗和雪柔的警惕始终让迈克尔的调查寸步难行。直到一天，迈克尔的女友无意在奥利弗的车后发现了一只可疑的包裹，然而就在他们还来不及弄清楚事情原委的时候，谋杀已经笼罩了这座城市……In suburban Reston, Virginia, George Washington University American History professor Michael Faraday is still mourning the death of his wife, FBI agent Leah Faraday, after three years. His inside knowledge of the agency colors what he teaches in his classes. Although on good terms with Leah's ex-partner, Whit Carver, and the agency in general, Michael wants the agency at least to acknowledge their responsibility in her death in the line of duty. Michael is moving on with his personal life, he being in a serious relationship with his former teaching assistant Brooke Wolfe. Although he likes Brooke, Michael and Leah's nine year old son, Grant Faraday, may not yet be quite ready for Brooke to be a permanent part of their lives. It is only in helping adolescent Brady Lang who he sees in medical distress that Michael meets his new neighbors, Oliver and Cheryl Lang, Brady's parents. In the process, Michael and Brooke becomes friends with the Langs, as Grant and Brady become friends. However, the more time that he spends with them and catches discrepancies in their stories, Michael becomes suspicious that the Langs may not be everything they appear on the surface. As such, Michael, against Brooke's concerns of invasion of the Lang's privacy, begins his own investigation of Oliver in particular. What Michael discovers has serious national security implications, as well as possible life threatening dangers to him, Brooke and Grant.
