Chris Morrell (John Wayne), 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. Meanwhile outlaw Sam Black is after the girl and her father as well, looking to steal the oil lease for himself. Along the way, he meets a lady who's the sister of Jim Moore, another bad hombre who's in cahoots with Sam Black, and an old friend who takes in Nina and helps Chris locate her father and fight off the various desperadoes.
