Engineer Edward Creighton (Dean Jagger) is part of a vast enterprise: stringing a telegraph line across America. When he has an accident in the field, Creighton is saved by bank robber Vance Shaw (Randolph Scott). Creighton later hires Shaw as a scout, despite his criminal past. As Western Union starts construction of the telegraph line through American Indian territory, Shaw's criminal past resurfaces when an old criminal cohort makes an appearance. Wikipedia
