In the years following the return home of the last U.S. troops who participated in ground war in the Persian Gulf, attention has turned from the historic victory to a strange new sickness the press has dubbed Gulf War Syndrome.

FRONTLINE tells the story of how Gulf War Syndrome came into existence, examining the psychology of war, the politics of veterans affairs, and the roles of the media and the biomedical research community.
