A dramatic story of the bad effect of unreturned love upon an unscrupulous person. Two sisters who are sheep owners have been pasturing their sheep upon the ranch of their next neighbor, who owns the only spring for miles around. Their neighbor sells his ranch, thus hazarding their right of pasture. His foreman, who is to be retained by the new owner, tells the girls that he can secure a continuation of their right, but only on condition that one of them marry him. Each indignantly refuses. He then drives their sheep from the place. Later one of the girls meets the new owner, a doctor, who being favorably impressed with her renews the right of pasturage. The foreman in revenge poisons the spring and the girl drinking of the water by chance is poisoned. The guilty person is discovered and tarred and feathered. The girl recovers and all is well.
