This series follows the Clampett family from the Ozarks to posh Beverly Hills after they strike oil and become millionaires. Banker Mr. Drysdale tries to keep them from foolishly spending their newfound wealth, and he also tries to "civilize" them -- usually succeeding in making a fool of himself in the process.

One of Jethro's school friends spends a day at the Clampett mansion, and the hillbillies show the over-protected boy how to have fun.

Jed takes over Drysdale's job for one afternoon and wins him the Banker of the Year title; Drysdale accidentally uses the wrong speech for his conference, and a new teller makes an impact.

Jethro is finally told that he can finish the fifth grade by Doctor Twombly, but the doctor still wants to see Grannie; her love potion for Pearl misfires, leaving Twombly confused.

The Clampetts take Jethro to Mrs. Drysdale's psychiatrist for an assessment so that he can pass the fifth grade; when Pearl accompanies him, she is worried about being asked to lie on the couch.
