Showdown

After a train robbery committed in New Mexico, a small gang sets-out to divide the loot. However, a disagreement over the shares causes one gang member, Billy Massey, to take the whole loot and run toward the Mexican border. The sheriff of Cumbres, Chuck Jarvis, learns of the train holdup and organizes a posse. Unfortunately, gang member Billy Massey is a very close childhood friend of the sheriff. No matter how disappointed the sheriff is, he's determined to do his duty and apprehend Billy. Local district attorney P. J. Wilson is a law-and-order hardliner with higher political aspirations. He demands the sheriff recover the railroad property immediately or else there will be consequences. Sheriff Chuck Jarvis hires a few Indian trackers and sets-out to find Billy. However, Billy's former gang members are also looking for him to recover the loot. Billy doubles-back to Cumbres and goes to the sheriff's house. While the sheriff's wife, Kate, serves Billy supper, the sheriff arrives and, after a short tense moment, persuades Billy to surrender and face a fair trial. With Billy in custody, sheriff Chuck Jarvis sends for the district judge and hires a lawyer for Billy. But strict district attorney P. J. Wilson is determined to hang Billy, no matter what. Now the sheriff has the double problem of protecting Billy's life from the lynching mob instigated by Wilson and from Billy's old gang members who are heading to town to kill Billy.
