Hardrock Jones and Rusty Bates have been prospectors and partners for thirty years. Hardrock has silver fever real bad. He wants to make a silver strike so bad that he can taste it. When eastern tenderfeet newcomers Dick and Bob Larrabee strike it rich, Hardrock can't stand it. He murders Rusty and puts the blame on the Larrabee brothers, hoping to take over their claim. The local sheriff seems honest but not too bright. Tonto will have to stay in town to make sure the brothers aren't lynched. Meanwhile, The Ranger will have to take a desperate chance to expose the truth.
