Mrs. Lowe is a widow who wishes to recover some gold stolen by her husband and then hidden away. She says she wants to return it to the bank it was stolen from and clear her family name. In order to do this, she persuades Lane (John Wayne) to ride into Mexico with her and recover the loot. Once they cross the border, they discover two very different pursuers: a large group of bandidos, and a lone horseman who seems to know their every move.
In this interesting western, sheriff Hayden's testimony leads to his own son's conviction for murder, despite the fact that Hayden is convinced of the boy's innocence. The sheriff tells of a deathbed confession that identified his son as the killer. However, Hayden is able to disprove the accusation and finally to track down the real culprit. While he is in pursuit, it is never clear whether the sheriff is going to kill the murderer in cold blood or bring him in to stand trial.
