Allen Jennings, whose father was murdered and his gold mine claim jumped, has been seeking the murderers for years. One day, a mine owner and rancher named John Sanderson hires Allen to evict neighboring ranchers Grace and Tom Henden, children of Jim Henden. Unknown to Jennings, Henden and Sanderson, whose real name is John Jasper, were once partners, and it was they who jumped Allen's father's claim.
