''The Man Who Came Back'' is loosely based on the Thibodaux massacre. This was the culmination of the largest strike in the sugar cane industry, when 10,000 workers stopped labor, and the first to be conducted by a formal labor organization, the Knights of Labor. With an estimated 50 or more African-American cane workers killed by white paramilitary forces, it was the second bloodiest labor strike in U.S. history.
