I don't think it was based on the "Twilight Zone" at all and I don't think it was one of the "charming" stories either, lol. (smile) In other words, it wasn't a horror tale.

Form what I remember about the episode, it was about an earth delegation (in the future) who wanted to mine minerals on another earth-like planet and the leaders of this other planet did not appreciate the earth humans intrusion. The main character, who wanted to develop this planet, was a capitalistic person who was an exploiter. The people on this planet were relatively peaceful and they just wanted to keep to themselves. The fact that they used bone for their flutes (including the man who wanted to mine their planet) was not necessarily typical of their culture, which was by and large peaceful and non-aggressive. At least, this was my impression, based on the story. The woman, who was part of the earth expedition team, fell in love with the leader of the planet and they listened to music together.
