Jed Clampett (Jim Varney), a hillsman of humble station, accidentally discovers oil on his land while shooting at a rabbit. Ozark Mountain Oil, interested in purchasing his land, offers him $1 billion for the property. Unsure of what to do, Jed consults his cousin, Pearl Bodine (Linda Carlson), during a family dinner. Pearl suggests a change of scenery for Jed's daughter, Elly May (Erika Eleniak), would be a good thing. Having made up his mind and accepted the money, Jed, his daughter, his mother-in-law Granny (Cloris Leachman), and his nephew, Jethro (Diedrich Bader), Pearl's son, load up Jethro's old, dilapidated truck with their possessions and move to Beverly Hills, California.
