John and Barbie Lomax (Friend and Hobson) have been married for almost 20 years, but the marriage has seemingly reached breaking point. After leaving the army, John has been working hard on making a career for himself as a barrister, which takes up all of his time and attention, leaving him exhausted and irritable. He acts intolerantly and dismissively towards Barbie and their three children, and the marital relationship comes under intolerable strain as the couple argue, bicker and snipe constantly at each other. Realising that the poisoned atmosphere is not good for the children to experience, they agree that in the circumstances divorce is the lesser evil.
