Chip has inherited a supposedly worthless gold mine from her father and Craig Allen is about to buy it. Roy suspects the mine may be valuable and using a clue left by Chip's father, investigates. He finds the hidden shaft that contains the gold and with the posse chasing him on a trumped up robbery charge, races to town with ore samples hoping to get there before the ownership is transferred.
