This story reminded me of The Others, the movie starring Nicole Kidman, made years later. Unfortunately, I predicted the ending from early on in this episode so the "twist" in the end wasn't shocking or unexpected. It was still a great tale and well written and performed.

A woman arrives home from wherever she has been only to find her precious home inhabited by a family of ghosts. After her initial outrage she learns to love them and grows fond of each one in turn. But, try as she might, she is unable to make direct contact with them. Predictable, with only a minor twist at the end.
