Mazursky's sharp satire tells of Bob (Columbo regular Robert Culp) and Carol (Natalie Wood: West Side Story, Brainstorm), an affluent and hip Californian couple who return from a free-thinking, free-love retreat, intent on having an open relationship. The more conservative Ted (Elliot Gould: MASH, The Long Goodbye) and Alice (Dyan Cannon, Heaven Can Wait) enjoy hearing about their friends amorous adventures, but the cat is set amongst the pigeons when they are invited to join-in... in bed!
