Most Americans believe the First Amendment is sacred and inviolate. But not since the 1950s has it been under such attack. This documentary explores the social and political trends that have shaped our attitudes about free speech—and which now threaten the very tenets upon which our country was built—through four case studies: an Arab-American educator who lost her job over a word; a high-school teen suspended for wearing a Bible-quoting T-shirt; a college professor fired for provocative essays written in the wake of 9/11; and two war protesters who were arrested and later made a shocking discovery.
