Duty Free was a sitcom starring Keith Barron and Gwen Taylor as a married couple who travel to Spain. Whilst in Spain they meet up with another couple played by Joanna Van Gyseghem and Neil Stacy.
The upshot is that the husband of one couple has an affair with wife of the the other couple without the other partners noticing - with 'hilarious' consequences of course.
