Can Bob and Carol's new thinking rub off onto best friends, Ted and Alice?Documentary film-maker Bob Saunders and his wife Carol attend a group therapy session that serves as the backdrop for the opening scenes of the film. Returning to their Los Angeles home, the newly "enlightened" couple chastise their closest friends, Ted and Alice, for not coming to grips with their true feelings.
