As crews labor to finish the first transcontinental railroad, Pony Express rider Davy Brandon (George O'Brien) returns to his hometown. There a childhood friend, Miriam (Madge Bellamy) -- fiancée of the chief engineer (Cyril Chadwick) and daughter of the principal contractor -- convinces him to aid in the project's completion. Although his father, a murdered railroad surveyor, passed on the knowledge needed for the job, a slew of saboteurs attempt to thwart Brandon in his efforts.
