When Stevie Appleby, Caroline's son, has a birthday party the same day as Little Ricky's, Lucy looks for unusual entertainment to lure the children.

George Reeves makes a special guest-star appearance in this episode.

As the Ricardos get settled in their new country home, they immediately wind up in a mix-up with their old friends Fred and Ethel Mertz.

At the same time, the Mertzes decide to trek to the country to visit the Ricardos, and what began simply becomes complicated.

Ricky is opening a new club, and he wants Bob Hope to appear at the grand opening. Lucy fears Hope won't appear because of her widespread reputation for monkey-wrench throwing, and wants to reassure him that this time she's butting out.

Suburban living gets Lucy into a flower-show competition, and she raises tulips with a vengeance as she tries to beat out her neighbor, Betty Ramsey, for first prize. Lucy asks Ricky to mow the lawn so that her garden will look just right. But he only mows half before taking off for a baseball game, leaving Lucy and Ethel to tiptoe through the tulips -- with the lawnmower.

Lucy decides that it would be nice to move to the country and prevails on Ricky to place a comfortable deposit on a big house. Ricky agrees and puts a down payment on a house in Westport, Connecticut. It is not long before Lucy changes her mind. Lucy, Ethel, and Fred put on disguises to try and help poor Ricky get his deposit back.

Lucy and Ethel will do anything to keep Ricky and Fred from judging a Miami Beach beauty contest (and end up being menaced on a seemingly deserted island as a result).

The Ricardos' apartment begins to resemble a pet shop when Little Ricky gets a puppy. Lucy and Ricky are both determined to get rid of the puppy after their son brings it home -- as are their landlords, Fred and Ethel.

With the best intentions in the world, Lucy somehow causes a misunderstanding with her neighbors, the Ramseys. It all starts when Betty Ramsey offers Lucy some advice and a wholesale deal on furniture. For a time, the Ricardos' whole future at their Connecticut home seems threatened.

After spending six whole weeks in their new Connecticut home, Lucy dreams of a night in New York City and it turns into a nightmare.

But difficulties arise when Fred Mertz gets nervous about pickpockets because he's carrying $500 in cash in his pockets.

Lucy tries to get in a skit with Orson Welles at Ricky's club, thinking it is a Shakespearean play that he will be doing. When Orson Welles tells Lucy she can be in the show, she calls her old high school drama teacher to tell her the news. Lucy's old teacher sends her whole drama class to Club Babalu to see Lucy perform. But poor Lucy! It turns out Welles only wanted her to be his assistant for a magic trick.

Mario, the Ricardos and Mertzes' gondolier in Venice, comes to New York to surprise his brother Dominic, but turns up at the Ricardos' apartment when he can't find him.
