Cisco is always handy for a worthy cause, no matter if the call is from the weak and defenseless, or is a powerful corporation.
A couple of guys damage the rails as part of a plan to rob a train that’s carrying a shipment of gold. Pancho and Cisco ride the train, on their way to Cactus Flats, just the place where the train robbery is to take place. Cisco has been placed on the train as security.
When the train goes through dangerous mountain passes where likely ambushes might occur, the outlook is that the worst is past. Nobody expects trouble near Cactus Flats. The train conductor tells Cisco about a feud between his family and another from back in the hill country of Tennessee.
Meanwhile, the bad guys get ready to flag down the train and do their worst. One of the bad guys, Link, has good enough standing in local parts to convince the sheriff to make him a deputy, and the plans continue. The train stops, and the conductor gets out to check on the trouble. To make it look legitimate, the bandits even call for a stage coach to transfer the gold. It all seems legitimate, and the conductor passes the word of the damaged track, and the bogus telegram to the crew.
Cisco and Pancho do their own investigating. Cisco gets suspicious and heads back to try to keep the gold safe. On the stage, the conductor rides next to Link, who rides with a kerchief over his face, presumably to keep the dust off, but Link knows that the two are from feuding families back East, so what will happen when Link reveals his identity?
Links plan is to take the gold, and set up his family rival to take the blame for it. Can Cisco get to the stage in time to prevent it? Our heros visit the sheriff and though he suspects them, Cisco and Pancho learn all the details they need to do their work. They make a break from the sheriff and hit the trail.
Cisco manages to head off the stage, and is just in time to swoop in and rescue the train conductor. The sheriff rides up and the whole story comes out in the open, and Cisco escorts the gold safely to it’s destination.
