Lucy fears that she and Ricky don't have enough in common, so she decides to pursue one of his interests: camping. Ricky and Fred don't want her (or Ethel, for that matter,) horning in on their summer retreat, so Ricky decides to take Lucy on a "trial run" in the woods and make her life miserable. But Lucy is wise to his plan, and guess whose life is made miserable in the end?
Lucy's sleepless nights with the new baby are exhausting, so the Ricardos hire a maid. Unfortunately, this new maid turns out to be a terrible shrew, who takes better care of herself than of Lucy or the apartment. Unable to get the gumption to fire her, Lucy wrecks the apartment, hoping it will make the maid quit.
Whether it's getting dressed or ordering dinner at a restaurant, Lucy seems unable to finish anything without changing her mind. Ricky loses his temper, so Lucy tries to play a trick with an old, unfinished love letter to a beau from high school. Fred warns Ricky of Lucy's plot, and Lucy is soon in over her head.
Because they both want to be president of the Wednesday Afternoon Fine Arts League, Lucy and Ethel both engage in cut-throat competition. Prior to the elections, Lucy and Ethel independently engage in a little "spywork." It seems that half the club plans on voting for Lucy and the other half plans to vote for Ethel. But there is one undecided vote--that of the new member, Ruth Knickerbocker. So Lucy and Ethel both go to extremes to sway Knickerbocker's vote.
When no one laughs at her jokes or wants her to be their bridge partner, Lucy comes to the conclusion that she is inferior to everyone else. Worried by Lucy's behavior, Ricky goes to the psychiatrist (or "fizz-a-key-a-tryst" as Ricky pronounces it,) to find the remedy. But it turns out that this doctor's "remedy" isn't exactly what Ricky had in mind.
Lucy's women's club wants to stage an operetta, but they're completely broke. (Lucy, the treasurer, seems to have spent it all to pay her own bills.) Thus, Lucy and Ethel write and star in the musical, but when their postdated check bounces for the costumes and scenery, the rental company repossesses everything in midperformance.
