Red Stanley's band has successfully robbed the express car and the members are making good their escape when they come upon Helen and her girl chum riding in the woods. The girls are set upon but they succeed by desperate riding in making their escape temporarily and, when danger seems near again, are saved by the approaching railroad detectives searching for the Stanley band. A running fight results in the capture of one of the band, but Stanley and his chief aide escape. Under cover of darkness, as Helen is working alone in the desolate station, the two enter and bind and gag her. They are driven off, however, by the approach of the night train. As she is riding the following day Helen is captured once more by Stanley, and handcuffed, while the horse's reins are tied to a tree. Helen sees the two crooks board a freight train preparing to start from the station. After a tense struggle she succeeds in getting her foot up so as to slip the horse's bridle off and, using her feet and voice to guide him, sets out at great speed towards the train. She drives the horse straight up the baggage platform and aboard a box car just as the train sets in motion. As the train speeds along she manages to loosen the gag and her cries bring the trainmen to the top of the box car. Guided by her directions they find Stanley and his aide and make them prisoners.
