No God, No Master (2014)

A plot to overthrow the United States government is uncovered in New York City in the summer of 1919 when William Flynn, a field agent for the Bureau of Investigation, is sent to investigate a bomb threat that has targeted some of America's most powerful politicians and leaders of commerce, New York millionaire John D. Rockefeller, Sr. among them. Flynn's investigation takes him on a journey into the underworld of homegrown terrorism and introduces him to a competitive culture of violence and murder. Greed, power, and politics are at the center of the story and Flynn must distinguish the villains from the merely discontented. Along the way, he discovers that terrorism has many faces and that a determination of guilt or innocence often lies in the psychology of fear that constricts individuals at every level of society.
