Moonrunners(1975)

You take a load of 200 proof corn liquor through a Georgia roadblock at 100 miles an hour and if you ain't a dead man, you're a moonrunner.

Grady and Bobby Lee run moonshine for Uncle Jesse, who prides himself on his old-school moonshining methods, and refuses to buckle in to the 'big business moonshine' of Jake, who controls these parts for New York mobsters
