An older lady - about 60 - comes to Dodge City claiming to be Kitty Russell's mother, Panacea Sykes. It turns out she is a mother of sorts. After Kitty's mother died she did take care of her for a few years. Kitty welcomes her, gives her a room and hospitality, and Panacea steals her jewelry, her liquor, and in general just abuses Kitty's hospitality from that point forward.
To be old, poor, and childless in 21st century America is bad enough, but I can just imagine how bad it was to be these things in the old West. But it is impossible to like this person who just grifts everybody for the entire episode.
Plus the episode really has no point, it just rambles along for its entire running time - not particularly funny, or poignant, or dramatic. The episode was directed by William Conrad, who played Marshal Matt Dillon on the Gunsmoke radio program from 1952 until it went off the air in 1961.
