The peaceful town of Silver Spur is horrified when the Holby family is murdered, and suspicion immediately falls upon a stranger who had recently been in town asking for directions to the Holby farm. Sheriff Jack Kincade tracks the man to a neighbouring town, where he finds the stranger who introduces himself as Snake Holby, the murdered man's brother. Jack takes Snake back to Silver Spur and locks him in jail for his own safety, as the townsfolk are convinced of his guilt, even though Snake claims that he didn't go to his brother's farm after all, being too ashamed of his shady past. Then a local boy tells the Sheriff how he had overheard three men talking about how they had massacred the family as an act of revenge. So who did kill the Holby family? Jack and Snake set out to discover the culprits, but the trail is not so straightforward....
