S1·E5 Showdown

Lambert is ready to kick himself when he picks up a hitch-hiker in the middle of the desert, and the hitch-hiker steals his car, leaving him without transportation. He starts to walk, but the sun is killing him slowly. Just when he thinks that he's found water, a cowboy stops him. Poisonous water...

The cowboy becomes Lambert's mentor, during the trip to wherever the criminal went. They find a ghost town in the desert, but the owner, a young woman, turns out to be on the criminal's side, locking them up in the jail...
