"Bad" Bascomb (Beery) is a notorious outlaw wanted by federal marshals after outwitting every group sent to capture him. He and fellow bandit Bart Yancey (Naish), a cold-blooded killer, have again eluded the marshals by joining a Mormon wagon train heading to Utah. They pretend to be helpful, and Bascomb becomes fond of an admiring little girl who attaches herself to him played by O'Brien. Beery eventually distances himself from Yancey by thwarting an attempted robbery and then saves the wagon train from an attack by Indians by riding to get help, before being taken captive by the marshal at the end of the movie.
