I am looking for the name of an old sci-fi show of which I saw only a part in the 90's (in USA). The part that I remember had this person (I thought it was some astronaut on a planet) walking through a city or a large open "strip mall", looking for a woman.
It seemed as is the man was on a planet that had previously had a large population of people but was now largely desolated, except for the buildings.
I think at some points during his search, the man had radio contact with the woman he was trying to find.
The show looked like it was a U.S. production, made in 70's (or in any case no later than early 80's), and in color. My impression was that this was a TV show rather than a movie.
What might have been the name of this show?
