Gaylord Duke, a (supposed) British third cousin of the Hazzard County-based Duke family, comes to visit. He asks Uncle Jesse for help in paying off a $30,000 tax bill for a parcel of land he claims he inherited. But is Gaylord really a Duke or a con man?

Millionaire C.J. Holmes is determined to retrieve his runaway daughter, who plans to marry a Hazzard County farmer. The girl later takes her appeal to the Dukes, explaining that her father wants her to marry within her social class and not someone involved in an unglamorous profession. Uncle Jesse ultimately meets with Mr. Holmes, and gives him a stern lecture about the dedication and self-sacrifice of farmers.

The Dukes try to reform an old-time moonshiner named Hard Luck Jones, who can't seem to shake off his love for stilling illegal whiskey. Things come to a boil when Hard Luck hijacks an armored personnel carrier to use as a mobile brewery. Bo and Luke are accused, and it's all they can do to convince their friend to give up his activities and avoid all of them being nabbed by federal agents.
