No God, No Master

The film is based on real events that took place in the United States during the 1910s and 1920s. America's wealthy elite begin receiving "gifts" in the mail—bombs. William Flynn, a specialist from the American Bureau of Investigation (the predecessor of the FBI), is brought in to investigate. Following the trail of the perpetrators, he encounters the lives of immigrant workers, their struggle for rights and dignity, anarchist theorists and bomb-makers, as well as the radical union Industrial Workers of the World (IWW).
