Admiral McKee (Tom Skerritt) is retired, when following the events of 9/11 he receives a call from the White House informing him that his commander in chief requires him to serve his country once again. Shortly after this he is sworn into office as a senior member of the Office of Homeland Security under Tom Ridge. Once in office Admiral McKee faces the challenge of organising this new office so as to prevent further terrorist attacks against the United States. With this in mind Admiral McKee's wife, Elise Mckee, recommends he speaks to his friend, NSA Agent Sol Binder.
