I seem to remember seeing a movie when I was a kid, which I assume (for some reason) was a TV movie.
And I seem to remember it was about a rich couple being terrorised in their home. A scene that's stuck in my mind is of the couple being threatened at gun point in their large garden beside a water fountain. I think maybe the woman in it had jet black hair. It was shown on (i think) ITV in the late 80s ealry 90s.
Anyone know what this was?
