This story has an almost identical plot to Run Away to Terror (1977) which also was written by Gerald Sanford. The two were broadcast two years apart.
Barbara Rush and Russell Johnson had been castmates twice before--in the sci-fi classic It Came from Outer Space (1953) and in an episode of Owen Marshall, Counselor at Law (1971) titled Words of Summer (1972), but with this pairing being for their first and only time as a romantic couple.
