Everyone is at Arnold's where Potsie and Ralph ask Richie if he wants to buy a chinchilla coat. Potsie bought two male chinchillas (Herman and Harry). Ralph tries to sell Fonzie a chinchilla seat for his motorcycle saying that he could be the Liberace of motorcycle riders. The Magnets come to Arnold's with Joanie and are smoking cigarettes. Richie is stunned to see Joanie smoking. Richie goes up to her and says she looks like a kid - an immature baby. A boy comes over and tells Joanie that he hardly recognized her and that she looks older - probably because of the cigarette. Joanie is smoking in her room when Richie comes in. Richie says she will become a chain smoker, and Joanie tells him to mind his own business. Richie covers up for Joanie when Howard and Marion walk in, and they say they will take his car away from him as punishment. Joanie admits it was her that was smoking. In a meeting downstairs, the family tells Joanie that smoking is not healthy. Howard forbids her to smoke anymore. Joanie says that she's older now and should be able to make her own decisions. Howard reluctantly agrees but tells Joanie that he and Marion don't want her to smoke. Joanie says she will think about it. Joanie sneaks downstairs at night to smoke in the kitchen where Howard spots her. Richie and Howard talk at Arnold's and ask Fonzie to talk to Joanie. Fonzie goes to talk to Joanie in her room and says that she isn't anybody until she does what she wants to do and that smoking ain't cool. Joanie says the Magnets are cool and that they'll dump her if she doesn't smoke. Fonzie says that her body will dump her if she continues to smoke. At Arnold's, Potsie and Ralph tell Al and Richie they are in the greeting card business. While sitting with the Magnets, Joanie lights up again but puts it out and says she doesn't want to smoke. Angela, of the Magnets, tells Joanie that she wishes she had the guts to quit because she is up to two packs a day. Joanie goes to talk to Jim at the jukebox, and then they dance. At the house, Joanie says she has given up smoking for good. Marion receives a call from Ann Hanson who wants to know if they are going to the Leopard Lodge party at the Pfister Hotel. Howard doesn't want to go, but says it wouldn't be right not to. Joanie says that he is doing the same thing she was doing - something he doesn't want to do just because everyone else does it. Howard tells Marion to say they aren't going despite Marion having spent $37 on a new dress.
