The Lineman's Peril

The smugglers seem in a fair way to escape on a stolen engine when Helen, unhitching a team from a nearby wagon, races down the road towards the railroad bridge from which a rope is hanging directly over the track. Standing astride the two speeding horses Helen leaps to the rope, and swaying in mid-air makes a perilous drop to the stolen engine as it dashes past.

Detective Strong is warned that an attempt will be made to free the crooks he is taking to the penitentiary. In spite of his vigilance, the prisoners escape when confederates start a gunfight on the train. Strong and his men scour the countryside for the fugitives.
