Set in 1960-1970 New York, this sexy, stylized and provocative drama follows the lives of the ruthlessly competitive men and women of Madison Avenue advertising.
In the third-season opener, Salvatore and Don take a business trip out of town. Pete Campbell and Ken Cosgrove worry about the changes at Sterling-Cooper and how the changes will impact them.
Don's father-in-law pays a visit to his daughter's family. Peggy works hard on a campaign while the firm tries to decide if they will accommodate an unusual request from a client. Elsewhere, Roger plans a wedding.
The writers make an attempt to stave off late-night boredom during a mandatory overtime session. Roger throws a party as Joan and Greg host their own party. Sally has a run-in with Grandpa.
Don and his father-in-law cross paths. Meanwhile, Peggy is in search of a new roommate; and a rich new client is excited to be doing business with the firm.
Sally's behavior causes concern for Don and Betty. Betty has an eye-opening dream that has a strange effect on her. Pete tries to work a new business angle in his dealings.
Don has a big meeting with Connie about their future relationship. Betty is the beneficiary of some interesting advice and Pete has a serious sit-down with some clients.
