"Come Out, Come Out, Wherever You Are!" is set in Poland Spring, Maine, where pretty young Marie Duplessis (Diane Baker) strikes the fancy of a smitten Linc (Glenn Corbett), as they prepare for her birthday party. She confesses to Tod (Martin Milner) that she doesn't know who she is, trying to be what every man wants her to be. Lon Chaney co-stars as Poppa Duplessis, Marie's father, who only began paying attention to his daughter after his wife left them both when the girl was only 9 years old. Linc really takes a beating on her behalf, but starts to understand her doubts after she abruptly leaves her own birthday party with another man (Alex Cord). This was Chaney's third episode of ROUTE 66, following "The Mud Nest" and "Lizard's Leg and Owlet's Wing," and one of his last television appearances anywhere. His alcoholic character has a European accent, lost his left hand (shades of "The Alligator Man") working at the saw mill, and bitterly resents his lost wife, but still engenders sympathy at the prospect of losing his daughter, hoping she doesn't turn out like her 'no good' mother.
