In the final episode of The Lucy-Desi Comedy Hour, Lucy embarks on one more grand scheme! A depressed Ricky, who continues to threaten to move back to Cuba because he doesn't have any television offers, has Lucy worried! When she opens a letter Ricky sent to his uncle, asking him for a place to live on the tobacco plantation, she enlists Ernie Kovacs and Edie Adams for help.
While the pair visits the Ricardos and Mertzes, Lucy suggests that all of the talented individuals perform. Of course, Ernie Kovacs quickly jumps up to perform magic trips. Then, Edie Adams (with Ethel on piano) sings a lovely version of "That's All." Finally, Little Ricky runs downstairs to play his drums for the gang. But when Ricky is about to play the guitar, Ernie and Edie must leave.
Next, Lucy receives a call from Ernie, saying he wants Ricky on the show. A mistaken Lucy and Ricky think that Ernie wants "Big Ricky," really he only wants Little Ricky. Lucy then goes to Ernie and Edie's house the next morning to try and convince them to hire Big Ricky, and makes the mistake of talking to Ernie before he has had his morning coffee. Ernie screams at Lucy to leave...But Lucy doesn't give up that easily!
Ernie will not speak to Lucy so she dresses up as Crandall, the chauffeur, with a plan to talk to Ernie in the car. But Ernie doesn't come to the car alone--Ricky is with him! The two have already decided that Ricky will also be on Ernie's t.v. show (with Little Ricky); but Lucy is too deep in her plan to back out.
Edie then phones Ernie and tells him what Lucy is up to. The two gentlemen decide to teach Lucy a lesson, which results in all three "men" sharing one hotel room. Lucy squirms for quite some time--refusing of course to change her clothes--until Edie calls the hotel and tells her that Ernie and Ricky know she isn't Crandall! In the end, Lucy has the last laugh, as she bluffs undressing, and the scene fades with Ricky and Lucy sharing one last t.v. kiss.
