U.S. Defense Intelligence Agent Clark Poundstone (Greg Kinnear) doesn't want to hear what Army Chief Warrant Officer Roy Miller (Matt Damon) has to say about not finding the weapons of mass destruction -- evidence that could launch a war -- he's been sent to Iraq to unearth. Why the cover-up? Rajiv Chandrasekaran's exposé Imperial Life in the Emerald City: Inside Iraq's Green Zone inspired this frenetic wartime drama. Paul Greengrass directs.
