Bonanza (1959) : 14x16

In what turned out to be the series finale, Little Joe is making a delivery for Ben when he meets Bill Tanner, a psychotic killer that is posing as a soldier he has killed. His delivery wagon stolen and sans supplies, food or water, Joe - whom Tanner has called his ""prey"" - tries to evade the well-stocked madman, who takes sadistic pleasure in his role as a predator.
