In the glamorous and ego-driven world of advertising, everyone is selling something and nothing is ever what it seems. Set in 1960 New York, this series reveals the lives of the ruthlessly competitive men and women of Madison Avenue's "Golden Age," where key players make an art of the sell while their private world gets sold. And no one plays the game better than Don Draper, the biggest ad man, and ladies' man, in the business.
