Little Joe stops a deranged homesteader from setting fire to the land around the Ponderosa and sets off a conflict.
For all those fans of TV making, there is a blatant cut around the four minute mark from an outdoor scene to a soundstage, right after Joe tries to reason with the dead homesteader's daughter. Fairly seamless in its execution. Aside from that, the main thrust of this installment centers around the daughter's resentment towards the rich Cartwrights (as usual, Joe takes her home to the ranch) and the culture conflict with her family. A too long ten minutes of air time is spent "cleaning her up". Of course, a nasty Kentucky clan led by a crabby grandmother invades, looking to avenge what happened to their kin.
Maybe the most interesting facet about this episode is the emphasis that the Ozark hill people have little in common with the settlers of the west - something that is kind of interesting to think about. Not a lot of detail is invested in it, however. Still, there is a lot of fun watching Joe deal with the girl as Ben engages in a patriarch vs. matriarch game of wits with the interlopers.
A happy conclusion results, a little of a let-down but at the same time, a sort of affirmation of peoples' common values.
