Tex Ritter is on the trail of a menacing phantom badman in this classic western whodunnit. Along with fellow Texas Ranger Dave Wyatt (Dave O'Brien), Tex pursues the ruthless Whispering Skull, a mysterious midnight rider who terrorizes homesteaders and kills anyone who stands in his way. It's up to Tex, Wyatt and their trusty sidekick Panhandle Perkins (Guy Wilkerson) to catch the culprit and stop a group of scheming varmints who cash in on the Skull's grip of fear with coach robberies and diamond heists. The film features two musical numbers from the crooning Tex, "In Case You Change Your Mind" and "It's Never Too Late," both of which he co-wrote.
