  Valerie Plame is employed by the Central Intelligence Agency, a fact known outside the agency to no one except her husband and parents. She is an intelligence officer involved in a number of sensitive and sometimes dangerous covert operations overseas.
  Her husband, Joseph C. Wilson, is a diplomat who most recently has served as the U.S. ambassador to Gabon. Due to his earlier diplomatic background in Niger, Wilson is approached by Plame's CIA colleagues to travel there and glean information as to whether yellowcake uranium is being procured by Iraq for use in the construction of nuclear weapons. Wilson determines to his own satisfaction that it is not.
  After military action is taken by George W. Bush, who justifies it in a 2003 State of the Union address by alluding to the uranium's use in building weapons of mass destruction, Wilson submits an op-ed piece to The New York Times, claiming these reports to be categorically untrue.
  Plame's status as a CIA operative is subsequently revealed in the media, the leak possibly coming from White House officials, including the Vice President's chief of staff and national security adviser, Scooter Libby, in part to discredit her husband's allegation that the Bush administration had manipulated intelligence to justify the invasion of Iraq. As a result, Plame is instantly dismissed from the agency, leaving several of her delicate operations in limbo and creating a rift in her marriage.
  Plame leaves her husband, further angered by his granting of television and print interviews, which expose them both to public condemnation and death threats. Wilson ultimately persuades her, however, that there is no other way to fight a power as great as that of the White House for citizens like them. Plame returns to him and testifies before a Congressional committee, while Libby is convicted of perjury and obstruction of justice and given a 30-month prison sentence, although President Bush commutes the jail time on Libby's behalf.
