Plot After a weekend of emotional honesty at an Esalen-style retreat, Los Angeles sophisticates Bob and Carol Sanders return home determined to embrace complete openness. They share their enthusiasm and excitement over their new-found philosophy with their more conservative friends Ted and Alice Henderson, who remain doubtful. Soon after, filmmaker Bob has an affair with a young production assistant on a film shoot in San Francisco. When he returns home, he admits his liaison to Carol, describing the event as a purely physical act, not an emotional one. To Bob's surprise, Carol is completely accepting of his extramarital behavior. Later, Carol gleefully reveals the affair to Ted and Alice as they are leaving a dinner party. Disturbed by Bob's infidelity and Carol's candor, Alice becomes physically ill on the drive home. She and Ted have a difficult time coping with the news in bed that night. However, as time passes, they grow to accept that Bob and Carol really are fine with the affair. Later, Ted admits to Bob that he was tempted to have an affair once, but did not go through with it; Bob tells Ted he should, rationalizing: "You've got the guilt anyway. Don't waste it." During another visit to San Francisco, Bob decides to skip a second encounter with the young woman, instead returning home a day early. When he arrives, he discovers Carol having an affair with her tennis instructor. Although initially outraged, Bob quickly realizes that the encounter was purely physical, like his own affair. He settles down and even chats and drinks with the man. When the two couples travel together to Las Vegas, Bob and Carol reveal Carol's affair to Ted and Alice. Ted then admits to an affair on a recent business trip to Miami. An outraged Alice demands that this new ethos be taken to its obvious conclusion: a mate-sharing foursome. Ted is reluctant, explaining that he loves Carol
