"Rebellion of the Hanged," alludes to workers who broke any rules being stripped to the waist and hung by their wrists high above the ground for countless hours on end. Some were even whipped while they were hanging Then they fought back.
This cruel punishment just made living and working in a Mexican mahogany plant that much worse. The workers were not certified slaves, but they may well have been, because quitting the job was impossible due to no way to get out of that part of the forest.
Pedro Armandariz is excellent as the father of a young boy, trying to support both of them. Ariana Welter is fine as a woman who arrived with him and the boy at the camp. In one sad scene, she tells the son that his father is working, when he really is hanging in pain.
This film is an indictment of conditions that existed at that time.
