S5E6 · Far Away Places

Complete story — includes the ending

Following an argument with Abe, Peggy pitches to the Heinz executives without Don and Megan, who are on an impromptu trip to Plattsburgh. After unsuccessfully selling her pitch, a frustrated Peggy has a sexual encounter in the theater with a young man. Ginsberg tells Peggy that he was born in a Nazi concentration camp and was adopted from an orphanage. Affected by the story, Peggy calls Abe to reconcile. Roger and Jane take LSD with a group of intellectuals, allowing them to speak candidly about their marriage for the first time; the two ultimately decide to separate. While visiting Howard Johnson's flagship Plattsburgh restaurant, Don and Megan fight when she expresses her frustration at having her needs and desires take a back seat to Don's. Megan makes a hurtful remark about Don's mother, causing Don to drive off without her; he later returns, only to discover that she is gone. After waiting for hours at the restaurant, Don drives home and finds Megan in their apartment; he violently struggles with her before tearfully admitting that he thought he had lost her. Returning to SCDP, Don is lectured by Bert for being on "love leave" after Peggy's failure with Heinz.
