Plot
Sintown is a ghost town that was once believed to have had a lode of silver, but the mines have been depleted. J. Malcolm Vanderpool's determined secretary Carol Martin impersonates Vanderpool's daughter and travels west to help her boss, who had invested in the mine. She discovers that Regan, a mining engineer employed by Vanderpool, has kidnapped Old Ed Carruthers, an old prospector who has found silver, but Regan wishes to keep the information secret for his own benefit. He puts Carol up in the haunted Hangman's Hotel until Roy Rogers, Old Ed's mule Genevieve and Roy's singing posse, the Riders of the Purple Sage, attempt to rescue the prospector and bring the villains to justice.
