A Touch of Class (1973)

American Steve Blackburn, in the insurance business, is married with two kids. Vickie Allessio, a self-described design "stealer" for a knockoff fashion house, is a recent divorcée with two kids. Steve and Vickie start running into each other more and more in their day-to-day London lives. When they do finally meet, Steve is up-front that he wants to have an affair with her; he has had affairs in the past whenever his wife Gloria isn't around, and right now she happens to be in the States visiting her old-money parents. Vickie is also up-front that she is amenable to a no-strings affair with him--under specific circumstance: it should be at least a classy short-term affair, meaning no cheap hotels; and preferably a weekend away, somewhere warm. Able to arrange a business trip to Málaga, Spain for a week, Steve convinces Vickie to change their agreed weekend to a week and spend it in the nearby resort of Marbella. However, one issue after another has the potential to derail the Marbella vacation and thus their affair, unless they can overcome all of the obstacles. If they can, they will need to decide if there is any sort of future for them in their real lives.
