Green Zone

On March 19, 2003, Iraqi General Mohammed Al-Rawi (Yigal Naor) flees his residence amid the bombardment of Baghdad. Before leaving the compound, he passes a notebook to his aide Seyyed, instructing him to warn his officers to get to their safehouses and wait for his signal.
Four weeks later, U.S. Army Chief Warrant Officer Roy Miller (Matt Damon) and his platoon check a warehouse for Iraqi weapons of mass destruction. To Miller's surprise, the warehouse has not been secured, with looters making their way in and out, as soldiers from the 101st Airborne Division are too few to do much. After a firefight with a sniper, Miller finds that the warehouse is empty, the third consecutive time he has found nothing. Later, at a debriefing, Miller brings up the point that the majority of the intel given to him is inaccurate and anonymous. High-ranking officials quickly dismiss his concerns. Afterward, CIA agent Martin Brown (Brendan Gleeson) tells him that the next place he is to search was inspected by a UN team two months before and that it too has been confirmed empty.
Meanwhile, U.S. Department of Defense official Clark Poundstone (Greg Kinnear) welcomes returning Iraqi exile politician Ahmed Zubaidi (Raad Rawi) at the airport. There Poundstone is questioned by Wall Street Journal reporter Lawrie Dayne (Amy Ryan). She says she needs to speak directly to "Magellan", but Poundstone brushes her off.
Meanwhile, while checking another unpromising site, Miller is approached by an Iraqi who calls himself "Freddy" (Khalid Abdalla). Freddy tells him that he saw some Ba'ath Party VIPs meeting in a nearby home. They include Al-Rawi and his officers and aides in Baghdad, who are discussing the current situation. Al-Rawi decides to wait for the Americans to offer him a deal, and attack if they don't. As the meeting ends, Miller and his men burst into the house. Al-Rawi narrowly escapes, but Seyyed is captured. Before Miller can extract much information, Seyyed is taken away by Special Operations personnel - however, Miller keeps Al-Rawi's notebook. Dayne complains to Poundstone again, but he states that the stakes are much larger than her role in selling newspapers.
Miller goes to Brown's hotel room in the Green Zone, where he tells him what happened and gives him the notebook. Brown arranges for Miller to get into the prison where Seyyed is being interrogated. Miller is then approached by Dayne, who questions him about the false reports of WMDs. Miller bluffs his way in to see Seyyed. Near death after being tortured, he tells Miller that they "did everything you asked us to in the meeting." When Miller asks what meeting he is talking about, he says one word: "Jordan." Miller then confronts Dayne about the bogus intel she published, but she refuses to identify Magellan, her source. After Miller tells her he suspects that Al-Rawi is Magellan, Dayne reluctantly confirms that Magellan met with a high-ranking official in February in Jordan.
Miller realizes that Poundstone's men are hunting Al-Rawi, and can think of only one reason: Al-Rawi confirmed there was no Iraqi WMD program and is now a major liability. Poundstone confiscates the notebook from Martin; it contains the locations of Al-Rawi's safe houses. When Miller tries to arrange a meeting with Al-Rawi, he is abducted by Al-Rawi's men following Poundstone's announcement of the decision to disband the entire Iraqi army. Al-Rawi tells Miller that he informed Poundstone that the WMD program had been dismantled after the First Persian Gulf War; Poundstone, however, reported that Al-Rawi had confirmed there were WMDs so the US government would have an excuse to invade. Poundstone's men attack the locations listed in the notebook. When they get to the general's hiding place, he flees, ordering one man to kill Miller. Miller manages to kill his captor and races after Al-Rawi. Miller finally captures Al-Rawi, but Freddy suddenly appears and shoots the general, stating that the fate of Iraq is "not his to decide." With his only witness against Poundstone now dead, Miller tells Freddy to flee.
Later, Miller writes a scathing report. He confronts Poundstone in a meeting and gives him the report, but Poundstone dismisses it, telling Miller that WMDs do not matter. Poundstone then rejoins the meeting, only to see Iraqi factional leaders reject Zubaidi, the US's choice as leader of Iraq, as an American puppet and storm out. Afterwards, Dayne receives Miller's report by email. The recipient list includes reporters for major news agencies around the world.
