Anna is the only daughter of "Pop" Grayson, proprietor of "The Top Notch Hotel" at Black Rock, Montana. Percy Eastman, a Yale graduate, lands in Black Rock in search of a fortune. He loses his heart to Anna and his money to Hoover and Sanders, who sell him a "fake" gold mine in which they have planted some rocks covered with gold paint. Anna determines that Percy shall make good and she persuades him to take a correspondence course in mine engineering. An accident leads to the discovery of a rich vein of copper in the "fake" mine. Leaving the girl to guard the palace, Percy rides to town and files his claim. Hoover and Sanders learn of the "strike" and try to "jump" the claim. But Anna, with true western grit, holds up the two bad men until her lover arrives and the girl and the man decide to join fortunes for life.
