Earl Dwire supplies a deliciously ripe performance as a half-breed outlaw in this early John Wayne Western from Monogram. After killing John's father, Zanti (Dwire) attempts to abduct pretty Ruby (Sheila Terry), but the girl is saved in the nick of time by John. Unfortunately, the bumbling sheriff (Jack Rockwell) not only mistakes John for one of Zanti's outlaws, but also accuses him of killing Ruby's grandfather, Dusty (George Hayes). The latter, however, is still very much alive and John tracks Zanti into the desert where the outlaw perishes after drinking poisoned water. With the boss villain dead, John goes after the entire gang who is eventually trapped in Dusty's mine.
