Hour Five explores the post-World War II era, when rising evangelist Billy Graham tried to inspire a religious revival that fused faith with patriotism in a Cold War battle with "Godless Communism." As Americans flocked in record numbers to houses of worship, non-believers and religious minorities appealed to the US Supreme Court to test the constitutionality of religious expression in public schools. And civil rights leader Martin Luther King, Jr. emerged as a modern-day prophet, calling upon the nation to honor both biblical teachings and the founders’ democratic ideals of equal justice.
