Scott Brady plays a decidedly mature Billy the Kid in this Columbia western programmer. According to this acount, Billy was just a mixed-up kid who was forced against his will to become a gunslinger. Billy's friendship with sheriff Pat Garrett (James Griffith), which has always been a matter of historical speculation, is deepened in the film, with Garrett reluctantly tracking Billy down after the latter has tried to avenge the death of kindly rancher John H. Tunstall (Paul Cavanaugh). British leading lady Betta St. John is cast as Billy's love interest (and the unwitting cause of his ultimate downfall) while Alan Hale Jr. is far removed from his Gilligan's Island role as The Skipper, cast here as a scowling heavy.
