The particularity of this episode is that it takes place almost entirely in a mine.and the overall topic is not so bad. It doesn't look as a kind of manufactured product, as many TV shows propose in their episodes. It is a question of hidden treasure, but we discover the explanation only at the end of the story. One of the villain, wearing a black suit, looking like a kind of Michael Pate, is particularely good. It reminded me some characters in one of John Sturges' westerns.especially one where it was played by William Campbell.
