The family's TV breaks down (thanks to Grampa trying to figure out how to change the channel after having to sit through an episode of the Spanish Bumblebee Man's sitcom), and they go buy a new one at an outlet mall in Ogdenville. Homer sees TVs from electronic brands, including Panaphonics, a parody of genuine products from Panasonic, Magnetbox, a parody of Magnavox, and Sorny, a parody of Sony. Then, the owner of the store lets them choose a TV from electronics "giant" Carnivale instead. While the family is there, Marge sees a $90 Chanel suit (marked down from $2800). After some coaxing from Lisa, she buys it, and is wearing it at the Kwik-E-Mart when she meets an old high school acquaintance, Evelyn Peters, who invites her to the Springfield Country Club. Marge begins visiting the country club with the family, and works hard to fit in with the snobbish members, finding less time for her children and spending it all socializing and altering her suit to appear like multiple outfits.
Meanwhile, Homer takes a fondness to the game of golf, meeting PGA Tour pro Tom Kite, who considers Homer to be a natural. When he discovers Homer showing off his impressive skills in a bathroom at work, Mr. Burns has Waylon Smithers schedule a match for the two. Burns appears to be an amazing player before it is revealed that Smithers has been cheating on his behalf for decades by secretly placing a ball on the green for each shot, leading Burns to believe that he has reached the green himself. Homer wants to reveal the truth, but is told that Mr. Burns will block the family's Country Club entry if he goes public. He reluctantly obliges to keeping the secret.
On the eve of the gala ball in which the Simpsons will be granted membership in the country club, Marge accidentally destroys the suit when Lisa is distracting her, and rushes back to the outlet mall to find another dress. Being unable to find one, she heads to a Chanel store to purchase an expensive replacement. As they approach the country club, Marge realizes how she has changed to fit in and decides that she would not want to join a club that would have the fictional, snobbish Marge, anyway. It is revealed in a cutaway scene that the country club members really did like them, and were really looking forward to the Simpsons' joining. The Simpsons then have dinner instead at Krusty Burger, reveling in the lower-class surroundings.
