A climactic donnybrook between hero Allan Lane and ace Republic villain Roy Barcroft is the highlight of this otherwise routine B-Western effort directed by John Ford's nephew Philip Ford. The railroad is coming to El Dorado on the Powder River and a phony agent, Devereaux (Douglas Evans), persuades the citizens that they must come up with $50,000 within three days or the building project may be in trouble. "Rocky" Lane, who is a genuine railroad man, knows that Devereaux is only an actor hired to swindle the good folks of El Dorado and that the real representative, Bob Manning (Bruce Edwards), may be in danger. The plot thickens when Manning's wife, Louise (Gerry Gantzer), arrives in El Dorado and immediately becomes a target of the swindlers. Using a phony telegram, Lane manages to flush out the leader of the gang, local tailor Shears Williams (Francis McDonald), but is then falsely accused of pocketing the $50,000 himself. Managing to prove his innocence, "Rocky" tracks down the villains in the tailor shop where a furious fight between good and evil ensues. Although stabbed in the shoulder, Lane succeeds in disarming his opponents.
