Chris Morrell, the guardian of half-Indian girl Nina, is helping her find her missing white father. so she can cash in on her late mother's oil lease. Outlaw Sam Black is after the girl and her father as well. Besides dealing with the Black gang, Morrell has to find another robber, Jim Moore, who switches clothes with him after he finds Chris unconscious from a fight with Sam Black. Along the way, he meets a lady who's the sister of Jim Moore, another bad hombre who's in cahoots with Jim Moore, and an old friend who takes in Nina and helps Chris locate Nina's father and fight off the various desperadoes
This time, the Duke ("Morrell") has a little more of a substantial story to get his teeth into, as he helps a young girl to track down her errant father so she can cash in on her late mother's oil lease. Meantime "Sam Black" (Yakima Canutt) and his fearsome gang are also on the hunt for the girl and her pa' and just in case there wasn't enough to cram into this 50-minuter, he also has to track down another robber who pinched his clothes. See, never dull, these! Again, Sheila Terry is the gal and Gabby Hayes the valiant stalwart. The dialogue isn't up to much, but there is no lack of action and though maybe just a little silly at the end; it's still - I think - one of the better Monogram Westerns Wayne made.
