White Lightning

Bobby "Gator" McKlusky is serving time in an Arkansas prison for running moonshine when he learns his younger brother Donny was murdered and that Sheriff J.C Conners was the one behind it. Gator knows the sheriff is taking money from local moonshiners, so he agrees to go undercover for the Feds and try to expose the sheriff. He gets a job running moonshine with Roy Boone and starts having an affair with his girlfriend Lou.
