As president of the Commerce Bank of Beverly Hills, Milburn Drysdale is determined to keep the fortune of one of its biggest depositors, Jed Clampett, in its place. From the day they move in, the Clampetts are wary of big city ways, and Drysdale makes it his personal mission to keep them from packing up the old pickup and moving back to Bug Tussle. Since his motivation is pure greed, it's fortunate that most of Drysdales attempts at manipulating the Clampetts backfire miserably. An expert suck-up, Drysdale is married to the impossibly snobby socialite, Margaret, and is stuck supporting her gad-about son, Sonny.
