The Single Track

As described in a film magazine, when New York City society belle Janette Gildersleeve (Griffith) is informed by her uncle Andrew Geddes (Kent) that her property in Alaska is threatened unless a railroad line is built to other holdings, she promptly closes her town house and, under an assumed name, takes a job as a clerk at the North Star Mining Company's store at Katalak, Alaska. There she encounters civil engineer Barney Hoyt (Travers) who is in charge of building the single track line. Jim Mallison (Betz) attempts to force his attentions on Janette and Barney saves her from further annoyance. The opposition company owning the mine at Unatik attempts to destroy the tracks and a bridge on the day the right-of-way is to expire by floating a raft with dynamite against the bridge. Janette and the family butler, who is posing as her father, destroy the raft and save the bridge. They also rescue Barney who was engaged in a hand-to-hand encounter with Mallison on the trestle.
