Selling vacuum cleaners door to door, Lucy (Lucille Ball) gives her first demonstration at the home of Mr. Mooney (Gale Gordon)--only to inadvertently suck up a rare stamp worth $3000. Determining that she left the stamp in a pile of dirt at the home of her next customer Mrs. White (Mabel Albertson), Lucy discovers to her horror that the stamp has been affixed to an envelope and sent to the post office. As a result, Lucy and Viv (Vivian Vance) must cook up another wild scheme to retrieve the stamp before it can be cancelled and rendered worthless.
