Lucy, Ricky, Fred, and Ethel are visiting San Diego. While Ricky rehearses a show with Maurice Chevalier, Lucy and Ethel cross the Mexican border to do a little shopping. Returning to the US, a stowaway boy is found in the Ricardo's car trunk by US Customes. With Lucy and Ethel in jail, Ricky, Fred, and Maurice come to the rescue. Unfortunately, now Chevalier is being held because he is not authorized to leave the US into Mexico. This sends Lucy off to a bullfight to find the American consul, only Lucy disguises herself as a matador, and ends up facing a raging bull.

Lucy & Ricky are off to sunny California for his latest motion picture, and rent their home to Danny Williams (Danny Thomas) and family. When Ricky's picture deal falls through, suddenly the Ricardo's are without a place to live. The Mertz' offer their home, and the two couples are now housemates. Unfortunately, Lucy becomes up in arms regarding the way the Williams are using their home, and soon makes a pest of herself. Culminating in a snow fight, the matter is finally settled in court.

Lucy is exasperated. Once again tired of her daily routine, she wants to give show business another try. Ricky agrees, and Lucy auditions as a ""Girl Friday"" for a morning news show anchored by Paul Davis. At the audition, Lucy suddenly realizes her age, and does a little fancy maneuvering for notice. All but giving up hope, she is startled to get the job.

Her first appearance is a disaster, but the viewers find it very humorous, and Lucy ends up with a long-term contract. Ultimately, Lucy misses Little Ricky and being a homemaker, and decides, after all these years, that show business really isn't for her after all. Lucy decides to quit, and goes home for some rest. With her sleeping schedule off kilter, Lucy downs a couple of sleeping tablets. A groggy Lucy is awoken by Ricky. They'll be sued if she doesn't honor her contract, and a heavily medicated Lucy is rushed to the studio.
