The Union Pacific Railroad loses $50,000 in gold bullion and assigns two undercover detectives to find the robbers and return the gold. Captain Street pretends to be a lawman chasing a wanted outlaw named Jim Parker, who is, in reality, his partner Sunset Carson. The trail leads to a Kansas town that is owned by one man, cattleman George Layton, but has been taken over by a saloon owner, Dalt Higgins and his appointed-judge crony, J. Frothingham Smythe, in his absence. Higgis is working secretly for Harvey Dawson, who wants the town because he knows the railroad plans to expand there and make it a railhead. (Another Republic western in which the locale in the title has nothing at all to do with the locale of the finished film. While this film is a remake and/or version of several other films, it is not a remake of Republic's 1936 "The Oregon Trail" with John Wayne)
