 A gang of bad guys menace a feller s gal. She hides in a freight car and a misstep sends the otherwise-empty train out of the station with the lever pushed to full speed. As the train gains speed, the captive s boyfriend must board the runaway train, repel the pursing gang, get his girl out of the box car, and somehow get the two of them to safety. Tunnels, a water tower, a steep grade, and a frayed rope complicate the hero s task.
