The Bus plot
"Members of a Bay Area chapter of the Congress of Racial Equality ride a chartered Greyhound bus cross-country to the March for Jobs and Freedom."
A group of white and black residents of San Francisco board a bus in the summer of 1963 for a three-day trip to Washington, where they will participate in the historic Great March. They discuss civil rights and racial integration, provide commentary and arguments, and sing folk songs and inspirational songs. The film is introduced by the Charles Franklin family and ends with the mass gathering at the Washington Monument.
