Mrs. Drysdale recommends Elly for a high-brow finishing school in hopes that humiliating her will drive the Clampetts away; but instead Miss Hathaway convinces the girls at the school that Elly is a fashion trend-setter. Elly invites the filthy rich Fenwicks over, thinking they're destitute.

Cynthia Fenwick makes her filthy rich mother dress in the "Clampett Look" when they visit the Clampetts, since she thinks Elly is a fashion maven. That only reinforces the Clampett's belief that the Fenwicks are poor. Cynthia mistakes Jethro for royalty and Mrs. Fenwick mistakes Mrs. Drysdale for a cleaning woman.

Mr. Drysdale needs investors for his real estate development project, so he enlists the Widow Fenwick, and aims to cement the deal by hitching her to Jed Clampett, who is looking to find a mother for his daughter, Elly May.
