Maurice Chevalier is slated to perform with Ricky's orchestra on the USS Yorktown, but soon finds himself smack dab in the middle of the Ricardos' and the Mertzes' misadventures as they head for Tijuana, Mexico.

The Ricardos prepare to go out of town for two months and decided to rent their home out to Danny Williams and his family. But when their plans fall through, Lucy and Ricky are forced to move in with Fred and Ethel in their guest house! Lucy, however, drives Danny crazy with her constant visits, and things get a bit out of hand. Danny Thomas, Marjorie Lord and Gale Gordon guest star.

The Ricardos and Mertzes head to Alaksa, but arrive a day early and their room is not ready; it is occupied by none other than Red Skelton, who generously shares his room with the foursome. Later, Ricky and Fred learn that they own land that is all ice and are constantly at each other's throats. Ricky and Fred's bickering causes Lucy to ask Red if he will buy the property, but chaos ensues.

Lucy gets tired of the same old daily routines that being a housewife has to offer, so she decides to get a job. While looking in the newspaper, she finds out that Paul Douglas is looking for a female assistant (a "Girl Friday"). Lucy lands the job; but on the first day, as usual, goofs up. However, the public thinks her blunders are scripted (and funny) and want more. She is signed into a contract with the show, but has mixed feelings when she begins to miss her family.

Harry Bailey, an agent of Ricky's, told the Ricardos that they can use his summer home for a vacation. But he also promises actors Ida Lupino and Howard Duff the same thing. Both the couples arrive at the cabin not knowing at first that the others are there. After the couples both decide to stay, the wives brew up a plan to spend more time with their husbands, who are more interesting in fishing than bonding.
