Tomboy Betty Jo (Linda Kaye) suddenly decides that she's interested in boys. The "boy" of her dreams turns out to be Steve Elliott (Mike Minor), the current beau of her older sister Billie Jo (Meredith MacRae). In a jealous pique, Billie formulates a plan to keep Betty and Steve apart--but as every good Petticoat Junction fan already knows, things have a way of turning out contrary to plan!
