The Parsons Land Reclamation Company hires "Drive" Garringer to rid the Arizona-Mexican border area of the Triple Arrow gang, who have been attacking their workmen. In Puma City, he discovers that the sheriff and leading citizens protect the outlaws. Meanwhile, Wilma Wharton, the daughter of an aged prospector, hoping to put an end to the advances of the gang leader, agrees to go through a fake marriage ceremony with another gang member, but later discovers that the marriage was performed by a authentic minister. Drive falls in love with Wilma when she hides him and gets a physician to attend to the wounds he received fighting the gang, but he leaves her when he learns that she is married. During a fight, both the gang leader and Wilma's husband are killed, and after she explains the reason for the marriage and the fact that she was married in name only, Wilma and Drive marry.
