Diana Scott is a beautiful, bored young model married to Tony Bridges. One day Diana meets Robert Gold, a literary interviewer/director for television arts programmes, by chance when she is spotted on the street by his roving film crew and interviewed by him about young people's views on convention. Diana is invited to watch the final edit in the TV studio, and it's there that their relationship starts. After liaisons in bleak hotel rooms, they leave their spouses (and, in Robert's case, children) and move into an apartment.
