The history of the Old West is the history of the railroad. When trouble makes an appearance with the railroad company, Cisco is on hand to lend his assistance.
There are plenty of characters who would want to block the railroad from going through, but Cisco helps, just because he’s a friend. Meanwhile, a couple of hardcases plan how they can disrupt surveyors from doing their job. It’s as simple as gunning them down, and taking their maps.
As our carefree heros ride along, Pancho gets confused over a common figure of speech, when they find the bodies of the dead surveyors. Will the train crew believe the fake survey report? Can Cisco convince the crew boss that there could be trouble?
Cisco has friends everywhere, and a surveyor friend in the near by town might be able to help determine the true boundary lines. Can the work crew be called back to work once they have been told to take a couple days off? Probably the most difficult thing for Cisco will be convincing the off duty workers to get back on the job. Good luck. The real killers even kill the crew bosss, and try to stir up the workors against Cisco and Pancho.
So what’s the big deal with getting the track to the state line? If the railroad company fails to get to the line, before the deadline, they stand to lose land grants. Cisco has the true story, and puts holes in the story the killers told. In a fistfight, Cisco proves who the better man is, and turns the killers over to the law.
Now the race is on for the last mile to the state line, and Cisco joins the crew to make the dramatic finish.
