Newly discovered "cousin" Jake Clampett soon has everyone but Jed thinking about and dressing for a role in a movie Jake wants to make. Mr. Drysdale hears that Jed is going to finance 10 million for the movie. Miss Jane comes up with a plan to put a stop to it all.
Note: Jake purchases a brand new 1964 Imperial convertible to improve Jed's image, but the car is never seen again – the Clampett family truck is Jed's choice of vehicle.
