When Ricky manages to sell the Pontiac convertible to Ralph Berger at M-G-M for more than he originally paid for it, he decides to return back East to New York City via train, utilizing the economical family plan.
But what about the Mertzes, who traveled to California in the car with them? Ethel: "I presume that when he sold the car, the back seat went with it!" Lucy assures her friends that Ricky hasn't forgotten them, but when the envelope containing only three Union Pacific Domeliner tickets arrive, it becomes painfully evident that Ricky has forgot about the Mertz's.
Feelings hurt, Fred and Ethel leave in a huff and prepare to journey cross-country on a fifty-dollar antique Harley-Davidson. When Ricky returns from the studio after saying his good-byes and learns of his oversight, he and Lucy rush to the hotel garage where they find their "former" friends ready to depart on the luggage-laden cycle.
The Mertzes' trip, however, is short-lived, Fred accidentally backs the vintage contraption into a brick wall. Ricky agrees to buy the Mertzes train tickets, but is unable to secure compartments for them, only a pair of upper berths.
Unaware of this situation, Lucy gives the expensive tickets to her friends and now has to figure out a way to switch them. Ricky: "You're vice-president in charge of sneaky switches." After much calculated confusion, including Ethel's mistaken belief that Lucy has the hots for Fred, they are ready to return home.
