In the eastern part of New Mexico is locate the little mining town of Gatlach. There, however, we find an active mining camp dependent largely upon the famous Gatlach mine for its existence. Living in the camp we find Florence, who is loved by Jake. Florence, too, loves Jake. A new superintendent arrives to take charge of the mining property. The new arrival meets Florence and the man and girl fall in love. Discontent among the Mexican and half-breed miners develops. They mutiny, coming to the office making demands which the super promptly refuses and orders them from the place. The ruffians withdraw to arm themselves and then plan an attack upon the office and the death of their boss. Jake overhears the plot, and while he has no love for Harry, determines for the sake of Florence to save them. He rushes to the office and warns them just as the mob appears. They are pursued and finally take refuge in a narrow pass. With only one horse, escape for the party is impossible. Jake forces Harry against his will to take the horse and Florence and escape. They depart seeking aid, which is found in the shape of a troop of cavalry out scouting. Thus reinforced, they rush back to Jake's aid, but too late, he has fought his last fight and given up his life for those dear to him.
