After growing tired of doing the dishes by hand, Lucy asks Ricky for an electric dishwasher, but he refuses. This leads to Ricky and Fred betting Lucy and Ethel that they cannot live the same pioneer existence as their ancestors.

Ricky needs a girl to act in a commercial for his television debut. Lucy immediately volunteers, but Ricky denies her. Lucy goes to the set anyway, and ends up in the sponsor's "Vitameatavegamin" health tonic commercial. As the tonic is 23% alcohol, Lucy soon ends up completely drunk.

Ricky and Fred think doing housework is much easier than earning money. Lucy and Ethel feel the opposite. So the men try doing the housework while the women attempt to earn a living by getting a job at a candy factory. Ricky and Fred find that they are no good at being housewives as they cause a huge mess in the Ricardo's kitchen, while Lucy and Ethel find themselves fighting against a speedy conveyor belt of chocolates that they have to wrap. Elvia Allman guest-stars.

Lucy has a salad dressing recipe that was given to her by her aunt Martha, and Fred tells her she should sell it. Thinking that they will become millionaires, they market the product as "Aunt Martha's Old Fashioned Salad Dressing," but have priced the product so cheaply that it will cost them rather than make them money.

After seeing Lucy and Ethel search their dollar bills for a newspaper's "Bonus Bucks" contest, Ricky finds out that one of his dollars is the winning bill, and decides to plant it in Lucy's purse to let her find it herself. After it inadvertently gets sent to the laundry, the Ricardos and Mertzes have to get it back before the contest is over.

Arriving in Hollywood, Lucy and the Mertzes go star-hunting at the Brown Derby restaurant. While there, Ethel has an interaction with Eve Arden, while Lucy annoys William Holden by staring at him from behind a potted plant and then accidentally getting him hit in the face with a pie. Ricky later meets Holden and brings him to their hotel room to meet Lucy, who must avoid being recognized.

Since Lucy is longing to appear in a movie, Ricky arranges for her to appear as a murdered showgirl in a film from his studio MGM, but the role and the costume are more than she can handle.

Lucy is determined to own a Don Loper gown and winds up being part of a "Hollywood Wives" fashion show while having a bad sunburn.

Carolyn Appleby, one of Lucy's friends from New York, is visiting and wants to meet some of the movie stars that Lucy has bragged about befriending, starting with Van Johnson, who is appearing at the hotel.

Before Carolyn leaves Hollywood, she wants to see all of the celebrities that Lucy claimed would show up for a get-together. Dressing up with masks of Clark Gable, Gary Cooper, Jimmy Durante, and other celebrities, Lucy manages to fool the near-sighted Carolyn. However, Harpo Marx shows up and soon discovers Lucy dressed up as him.

Ricky has completed his movie for MGM, but Lucy and the Mertzes convince him to let them stay in Hollywood for one more week. While sight-seeing, Lucy discovers that the cement slab with John Wayne's footprints and signature in front of Grauman's Chinese Theater has become loose. Lucy talks Ethel into helping her steal the slab to keep as a souvenir, and as they make their get-away, Lucy gets her foot caught in a bucket of cement. Ricky demands that they return the slab to the theater forecourt, but while trying to return it, Lucy and Ethel accidentally destroy it.

The police have been called to investigate the missing cement slab of John Wayne's footprints and signature. Ricky gets Wayne to help by having him create a duplicate slab with his footprints and signature to replace it, but in the process they encounter several setbacks. John Wayne guest-stars.

In this Brigadoon-inspired episode, complete with musical numbers, Lucy dreams that she visits her ancestral village in Scotland. The villagers are delighted at her arrival, as it is once again the year when they must sacrifice a McGillicuddy to a man-eating, two-headed dragon (Fred and Ethel)--and until Lucy showed up, the clan was believed to be extinct. Lucy hopes that Scotty McTavish McDougal McCardo (Ricky) will be able to fight the dragon to save her life. (Goof: McGillicuddy is an Irish surname.)

The Ricardos and the Mertzes arrive in Paris, and when a man outside the American Express office offers to exchange money for Lucy, she ends up in jail for passing counterfeit francs.

En route to Rome, an Italian movie producer offers Lucy a role in a color film called Bitter Grapes. Not realizing that it is a symbolic title, Lucy decides to take a job in a vineyard to do research for the role. She ends up stomping grapes and picks a fight with her fellow stomper. She then misses out being selected for the role due to being stained blue from the grape vat.

Lucy, Ricky, Fred and Ethel reminisce (via flashbacks of previous episodes) as they trim the tree on Christmas Eve. The flashbacks, all from season 2, include Lucy telling Ricky about her pregnancy in "Lucy Is Enceinte," Lucy, Ricky, Fred and Ethel singing in a barbershop quartet in "Lucy's Showbiz Swan Song," and Ricky, Fred and Ethel frantically preparing for Lucy's impending labor "Lucy Goes to The Hospital".

Lucy promises to produce Superman (George Reeves) for Little Ricky's fifth birthday party, but must make alternate plans when he is unable to attend. She hastily tries to impersonate Superman herself, but gets locked out on the ledge of the apartment. Note: George Reeves did originally receive voice-over screen credit for this episode, although it was subsequently cut from the syndicated version. After the closing credits, the disclaimer appeared on the screen that said: Superman Character, Feats and Narrative Copyrighted by National Comics Publications, Inc., 1956

Lucy jokingly dons a loving cup on her head that Ricky is supposed to present to jockey Johnny Longden, but then she cannot get it off.
