Mary is hosting a large party at her apartment. One of her guests, Sue Ann Nivens, who hosts the Happy Homemaker Show at the station, is offered a ride home by an unlikely source: Lars, Phyllis' husband. A few hours later, Lars telephones with a story about why he has yet to return home, a story that is obviously a lie to Mary and Rhoda, but to which Phyllis is seemingly oblivious as to the implication of something going on between Lars and Sue Ann. Every indication is that Lars and Sue Ann are having an affair, which is confirmed by a series of Lars/Sue Ann sightings. Phyllis is still oblivious to the affair until a clueless source spills the beans directly in front of her. To save her marriage, Phyllis' initial reaction is to become more like a real happy homemaker. But she decides to take more direct action, with support from Mary.
