This film consists of two unedited clips from Part 2 of the Public Broadcasting Service (PBS) American Experience documentary series, "Chicago: City of the Century". It describes the railroad strike of 1877, the development of the labor movement in Chicago, the eight hour day movement and worker protests at McCormick Reaper factories, the bomb that killed Chicago police at Haymarket square, and the execution of Chicago anarchists whose writings and speeches were blamed for the bombing. It concludes by referring indirectly to the work of labor movement leaders worldwide to honor the Haymarket Martyrs and the Eight Hour Day Movement with International Workers' Day-- also known as Labor Day or May Day. The film was written, directed and produced by Austin Hoyt.
