To promote the upcoming production of "Don Juan," The studio arranges for Ricky (Desi Arnaz) to appear in some publicity photographs, in which he is surrounded by a bevy of gorgeous starlets. Lucy (Lucille Ball), of course, is quite upset by this turn of events, and even more so when Ricky is required to attend a movie premiere with those selfsame starlets. When Ricky fails to return home from the premiere, Lucy jumps to the conclusion that he has left her in favor of one of the younger women -- and the mess isn't straightened out until the very end of the episode. ~ Rovi
