Set in 1960 New York City, "Mad Men" explores the glamorous and ego-driven "Golden Age" of advertising, where everyone is selling something and nothing is ever what it seems. And no one plays the game better than Don Draper (Golden Globe - winner Jon Hamm), Madison Avenue's biggest ad man - and ladies' man - in the business.

Don continues to conceal his increasingly complicated personal life, even in the face of Roger's invitation to open up. Meanwhile, Peggy pines for the absent Pete - still on his honeymoon - while fending off the advances of several of the men of Sterling Cooper.

Pete (Vincent Kartheiser) returns from his honeymoon, excited about his new marriage, but conflicted about his past encounter with Peggy. After his business relationship with Rachel (Maggie Siff) takes an unforeseen turn, Don attends a party which further illuminates his increasing dissatisfaction with his present life.

Pete's professional and personal lives become more complicated as he struggles to assert power in both. While facing pressure from his wife regarding a new apartment, he further alienates Don and endangers his own position at Sterling Cooper.

After Don wins an award, his photo is featured in "Advertising Age." Don must deal with the fallout as the photo brings back a past he isn't ready to confront. Ken gets a short story published in the Atlantic Monthly, inciting jealousy among his colleagues and driving Pete to make an unorthodox request of his wife. Peggy overhears a startling conversation in the office and shares the secret with Joan.

A taboo office romance is revealed. At a brainstorming session, Peggy proves to be more than a secretary, opening up new opportunities for her at Sterling Cooper. Meanwhile, Rachel faces her conflicted feelings for Don after he seeks out her advice on a new campaign.
