A soldier discovers how elusive the truth can be in this first major film about America's role in the Gulf War. Lt. Col. Nathaniel Serling (Denzel Washington) was the commander of a unit during Operation Desert Storm who mistakenly ordered the destruction of what he believed to be an enemy tank, only to discover that it actually held U.S. soldiers, including a close friend. Since then, Serling has been an emotional wreck, drinking heavily and allowing his marriage to teeter on the brink of collapse. As a means of redeeming himself, Serling is given a new assignment by his superior, Gen. Hershberg (Michael Moriarty). Capt. Karen Walden (Meg Ryan) was a helicopter pilot who died in battle during the Iraqi conflict, and the White House has proposed that Walden be posthumously awarded the Congressional Medal of Honor. Serling is asked to investigate Walden's actions on the field of battle, but he quickly discovers that no two stories about her are quite the same; Ilario (Matt Damon) says Walden acted heroically and sacrificed herself to save the others in her company, while Monfriez (Lou Diamond Phillps) claims she was a coward who was attempting to surrender to enemy troops. Meanwhile, reporter Tony Gartner (Scott Glenn) is hounding Serling, trying to get the inside story on Walden and on Serling's own difficulties. Matt Damon lost 40 pounds to prepare for his role in Courage Under Fire, which resulted in a potentially life-threatening illness for the young actor.
