Peggy is given the opportunity to write copy for a new weight loss device that everyone knows is useless. She finds an interesting use for it, however. Afraid of losing the Lucky Strike cigarette account, Bert Cooper gets Roger Sterling to come in for a one-hour meeting but he has another attack. Don Draper becomes a partner and takes over for his friend Roger, but some of the ad men are sharpening their resumes nonetheless. Pete Campbell wants a promotion but Draper doesn't seem too interested. Pete sneaks into Don's office and takes home a parcel sent by Adam addressed to Don that the mail room boy comes to deliver.
It's been one month since Roger's heart attack, he who is still recuperating. This situation negatively affects Joan's outward emotions, and may negatively affect the one account with which Roger is intimately involved, one of Sterling Cooper's largest: Lucky Strike. Bert has a short term solution that may or may not work to appease Lee Garner, Sr.'s concerns. As a reciprocal favor, a competing ad firm has provided Sterling Cooper with a new account, for a new weight loss device with no proved research that it actually works or reliable testimonials. The creative team decides to give it to Peggy to work on, she unaware that they chose her for more reasons than the good work she did on Belle Jolie, or that it is a device targeted primarily at women. Peggy ends up having a different than publicly advertised effect from the device, which may pose a problem or provide an opportunity. In advancing her career, Peggy finds that she is caught between her known world of Brooklyn versus her emerging world of Manhattan. Roger and Peggy's situations in combination may affect staffing at the office, upon which Pete hopes he can ride the wave. Don and Rachel continue their affair, each trying to figure out what it means in their respective lives, while Betty fantasizes about an extramarital opportunity of her own based on the heat wave that has settled over New York, that heat wave despite it being October. And Adam makes one last overture to connect with Don, his biological brother.
- Adam Whitman, unshaven and dressed in a dirty suit, hands a shoe box to a hotel manager and asks him to mail it for him. The package is addressed to Donald Draper at 405 Madison Avenue. It costs 40 cents, but Adam hands the man a $5 bill.
Back in his hotel room, Adam throws the pile of bills that Don gave him on the table. He places a note that says, "Enjoy next to the pile". Then, he removes his belt and pulls a chair next to a ceiling pipe. He threads the belt around his neck and around the pipe before kicking the chair out from under him. His feet dangle as he hangs himself.
Its October at Sterling Cooper, and Roger is still out recovering. Joan prods Don about his condition but is flustered by her own lack of aloofness.
The ad men congregate in Dons office. On the coffee table is a pink plastic belt shaped like womens panties with a small control box and electric cord. After they timidly inspect it, they discover that its a weight loss invention. Whether it actually causes weight loss is yet to be determined, and Pete is skeptical to promote it. It might be a lightning rod for the government and other people out to kill advertising, he says.
Just then, Peggy walks in. As she leaves, the men jokingly suggest that she might be a good candidate to try the Electrosizer. Fred, however, thinks shed be able to put her creative talents to work by testing it out. Later that night, Peggy sits in her bedroom, papers spread on her bed. She decides to give the contraption a try. Peggy turns the dial, and immediately becomes aroused by the vibrations. She peels it off in a hurry.
In another bedroom, Don stares at Rachel. She admits that she thinks about them being together. "I dont know if I understand how this works or where it goes," she says. "I´m worried this is a fantasy."
The next day, Peggy awkwardly shares with Don what shes discovered about the Electrosizer. She struggles to explain that she felt something that most women would like to feel. It vibrates, and that coincides with how you wear it, she says. Its probably unrelated to weight loss. Don realizes this new benefit and asks Peggy to figure out how to put it into words.
Cooper tells Don that he just spent the morning talking the Lucky Strike account "off the ledge." They recently lost a lawsuit and they are nervous about continuing to do business with Sterling Cooper due to Roger's heart attack. They´ll need to be ready for a big lunch meeting tomorrow -- with Roger.
At the Draper residence, Betty gets a visit from a door-to-door air conditioning salesman named Bob Shaw. When Betty says shes not interested, he asks to come in for a glass of water. He persists, but she doesnt think the Indian Summer will last much longer. He continues to explain how cold air is escaping through their windows and offers to take some measurements. She accepts the offer, and as they both walk up the stairs to look at the bedroom window, she hesitates. "You know, my husband, I think he´d rather go to Sears," she says, forcing him to leave.
That night, when Betty mentions the salesmans suggestions, Don fumes over her letting a stranger into the house.
The next day, Roger -- washed out and tired -- walks with Mona into the bullpen for the first time since his heart attack. A crowd gathers and applauds as he, Don and Cooper go into Rogers office.
Joan enters with instructions to help with his coloring. As she applies foundation to his cheeks, they admit they missed each other. "I´ve had a lot of time to think about the things I´ve done and been sorry about," he says. "And being with you is not one of them." Joan wells up with tears.
Men congregate in the conference room for the meeting with Lee Garner Senior and two other Lucky Strike executives. Don and Roger, all smiles, enter and get down to business. Anti-smoking legislation is in progress, but it could be a few years before they put warning signs on packages. Then, Roger lights up a cigarette as he bites into his pastrami sandwich. "Oh, oh Jesus!" he shouts, clutching his chest. Once again, Roger is wheeled away by ambulance drivers.
Harry, Paul, Pete, Ken and Salvatore sit in Petes office, debating what might happen to the company. Sal jokes that he already sent out his resume, but Harry thinks Don will become partner. When they all start wondering if Don likes them, Pete shrugs in annoyance.
That evening, Peggy sits at La Trombetta, a seafood restaurant, with her date Carl Winter -- a blue collar truck driver in his best suit. When Peggy mentions how her Belle Jolie copy will appear in some high-fashion magazines, Carl remarks that advertising is simply a lot of people screaming at you from the walls and television. She´s offended, but he reminds her of her reaction when he said he drives a truck for a living. "You can act like youre from Manhattan, but you don´t look like those girls," he says.
Angry, she gets up to leave. "Those people in Manhattan?" Peggy says. "They are better than us. They want things they haven´t seen."
Later that night, Don calls Dr. Wayne. He´s angry that Betty is in worse shape than she was before therapy. After hundreds of dollars, all you´ve managed to do was make her more unhappy, he says. Dr. Wayne suggests moving toward psychoanalysis, which is at least three visits every week.
The next day, Peggy gives her presentation of the new product. "Women lose weight so they´ll feel good about themselves," she says. "Combined with a sensible diet, the Rejuvenator -- you´ll love the way it makes you feel." They love the pitch but are still confused as to what it actually does. "From what I understand, it provides the pleasure of a man without the man," Don says. He offers a critique. It needs a new name and a clever code word so women will know its real utility.
In Ossining Betty attends to the laundry. When the washing machine goes into its spin cycle it begins to clatter against the floor and wall. Leaning it to steady it, she feels the vibrations and closes here eyes as she fantasizes about having sex with the air conditioning salesman on top of her dresser.
Back at the office, Peggy timidly asks for her own desk. She´s interrupted when Cooper asks to speak to Don in private. He offers to make him a partner. When Don accepts, Pete is the first to congratulate him. Don, high off his promotion and raise, gives Peggy a raise, and the rest of the day off. Pete sneaks in to Dons office to sit behind the desk. Just then, the mailroom boy delivers the package from Adam.
Curious, Pete shakes the box. He takes it with him as he leaves.
