After binding Helen to prevent her from stopping the express train to have it await an armed guard, crooks board the train, disable the messenger and dynamite the safe. Helen later takes a short cut in an auto and overtakes the train, but the crooks leap from the speeding train into her car before she can warn the engineer and train crew. At the point of a gun the chauffeur is made to follow the crooks' orders, but at the right moment Helen leaps from the speeding auto, the chauffeur turns the car to the edge of the cliff and then jumps for safety himself. The car somersaults down the forty-foot cliff burying its occupants beneath it.
