In Prohibition-era Georgia, John Wallace ruled Coweta County as a ruthless moonshiner and murderer who controlled local law enforcement. In April 1948, Wallace and three accomplices murdered cattle farmer Wilson Turner. But Wallace made a fatal mistake: he dumped the body in Meriwether County, where Sheriff Lamar Potts refused to be intimidated. The investigation and trial that followed exposed decades of corruption and became one of Georgia's most famous murder cases.
