Federal marshal Nevada Jack Mackenzie (Johnny Mack Brown), working undercover, comes to the aid of the nephew of old friend Sandy Hopkins, who is now retired, when the nephew is cheated of his money and later ambushed after his herd of cattle is rustled. After Sandy is summoned, he arrives in the guise of a dentist and uses this undercover role to investigate. Another enjoyable entry in the series from Monogram, with an unsurprising, but pleasing, little romantic subplot for the nephew as well.

  Recommended. Otto finds this one pleasing enough to relax.

Movie 46 for 2021.
