'The Fighting Man' follows the fortunes of a small group of political exiles as they attempt to overthrow the brutal and repressive regime in their native Guatemala. Idealists, not warriors, they require the services of a fighting man to direct their enterprise. Their search brings them to Gordon Benjamin Brown, a military misfit whose career has ended in disgrace; and under his leadership their makeshift army marches on Guatemala City, growing in numbers along the way. At first their progress seems unstoppable, but as events move towards a gripping climax it becomes clear that the Guatemalan army is not the only enemy that they have to overcome; other agencies are working to destroy them.
