In the Season 4 opener, Don's reluctance to talk about himself jettisons a prestigious trade-paper interview that the company was hoping would be a boon to business. Meanwhile, the "wholesome" manufacturer of two-piece swimsuits wants to hire the firm but doesn't want a sexy ad campaign; Pete and Peggy stage a stunt in an effort to secure more money from a meat-company client; and Roger plays Cupid for Don.

Don plans a jaunt to Acapulco, while back at the office, Lane and Joan get into a serious disagreement.
