Boss Hogg and Uncle Jesse get into a tiff trying to decide who was the better moonshine driver back in the day. To resolve their feud they decide to have a moonshine running race against each other, to settle to skirmish once-and-for-all. As expected though, Boss Hogg wants to ensure he'll win so he goes out of his way to cheat, lie, and sabotage Jesse's car. It doesn't work. Jesse wins and the Dukes prevail despite the odds, an angry neighbor-county Sheriff with a penchant for stabbing thins with a railroad spike chases them, the racers drink beer before racing, engines scream, and cowboy-boot wearing stunt guys jump onto moving cars with reckless abandon. Hijinks ensue.
