Betty's father pays a visit; the Drapers dine with the stuffy new British boss (Jared Harris) and his snobby wife; the firm contemplates whether to accede to an unusual request from a client; Roger takes charge of arranging a wedding; and Peggy's personal involvement in a campaign leaves her greatly affected.

Don crosses paths with his father-in-law (Ryan Cutrona); Peggy searches for a new roommate; and a new client with money to throw around is very excited about doing business with the firm.
