Despite Martin’s constant reassurances that her findings of pornographic material are harmless, Frances slowly realises over a number of years that her husband is addicted to pornography. With the new computer age she discovers his addiction is worse, and is now coupled with alcohol dependence. She can take no more lies and deceit, and wants out of her 30-year marriage. Instead she becomes attracted to Graham, a work colleague, who seems as normal as normal can be.

Martin is horrified that his wife wants to leave him, and seeks counselling help from Rhona, who encourages the couple to go away on holiday together. However, events on holiday do not go to plan, leading Frances to eventually discover the shocking reason behind Martin’s addictions.
