U.S. Marshals Nevada Jack McKenzie (Johnny Mack Brown) and Sandy Hopkins (Raymond Hatton) are sent to investigate a series of bank robberies and stage holdups, arriving just as the latest crime occurs. As is common with this series, they both go undercover: Nevada follows the escaping crooks and tries to get in with the gang, while Sandy, who successfully downed one of the felons, ends up pretending to be a cobbler. Separately and together, they work to learn the identity of the leaders of the criminals, and in particular that of the inside man at the bank, while trying to foil any further thefts; experienced viewers will have little trouble in spying the culprits. Brown and Hatton work well together (even if Hatton was even more at ease in the earlier Rough Rider series, in which he played the same character), and the supporting cast members — especially Edmund Cobb — do a solid job. Kirby Grant has a modest role as a bank clerk but gets little opportunity to shine.

  Mildly recommended. Otto judiciously thinks this movie is OK.
