The Moonshine War

John "Son" Martin makes moonshine whiskey, owning and operating a profitable still in Prohibition-era Kentucky. One day, he gets a visit from an old Army acquaintance, Frank Long, who is now an Internal Revenue agent. Frank is willing to look the other way in exchange for a percentage of Son's business. He sends for the dangerous Dr. Emmett Taulbee, who uses more violent methods in getting what he wants.
