Phil Dolan (aka Black Jack because of his talent at cards), Nancy Dolan, and a rustler all have a piece of a silver dollar with each piece having a portion of an indented map of an ore mine. Phil has to rescue Nancy from the rustlers to keep their portions of the silver dollar from the rustlers. The sheriffs's pose captures the gang of rustlers just as they reach the ore mine ensuring their claim to the mine.
