The Williams family made Carolina whiskey for generations until Prohibition shut it down. When moonshine legend Tim Smith brings backwoods knowledge to recreate the old family recipe, he discovers one of the most important distilleries in US history.

Tim Smith must rescue the worst distillery he's ever seen, starting at the bottom; while his crew transforms a barn into a Prohibition-style speakeasy, Tim applies his backwoods know-how to reengineer the still, taking the owner's gin to a new level.

After a first-time distillery owner invests $2 million in a pot still and hires rookies to run it, Tim Smith realizes their recipe may blow up the building; Tim must help them rediscover their backwoods roots and learn to make Carolina whiskey.

The Bondurant brothers are the most notorious bootleggers of the Prohibition era, turning Franklin County, Va., into the Moonshine Capital of the World; now, Tim Smith helps a descendent turn the family business into a hallmark of American whiskey.
