Granny receives a box from Cousin Pearl in the hills. One of the items in the box is an old fashioned crank telephone. Granny asks Jethro to hook it up to a party line on the pole so she can listen in on the party line.

Jethro is in love with Susie, the carhop waitress at the local drive-in, but Susie keeps rejecting his advances. Jed advises a dejected Jethro to take dating advice from Dash Riprock, the movie star/playboy neighbor to the Clampetts. Dash advises Jethro to buy a convertible, invite Susie to go on a double date with Elly Mae and him, and even lets Jethro use his bachelor pad. Despite Dash's efforts, Jethro still can't get past his hillbilly ways to Susie's heart.
