Frontier detective Mahoney takes on the search for four heirs to the fortune of an old prospector who has been killed by three thugs. Along his travels he meets and falls in love with Hunter and finds the heirs. He then discovers that Stone, one of the beneficiaries, was among the killer
pack that did the prospector in, and Stone now asks forgiveness. Most of the excitement in this one is in the title, and that has little to do with the story.
