One day while Calamity Anne is standing in front of her shack, Tommy nibbling grass at her feet, a lawyer comes up and informs her that Miss Ann Thompson is heiress to a large estate. Calamity claims to be the heiress and is overjoyed at her good fortune. She bids farewell to the cowboys and goes to claim the estate. She arrives and is met by her uncle’s two lawyers, who escort her and Tommy to the estate. Calamity is much impressed by the vastness of her fortune and when the lawyers suggest that she go into society, she assents readily and employs a social secretary to smooth the way for her. Calamity rides about the grounds of her estate on Tommy, the irate footman trotting at Tommy’s heels. The servants are nearly all driven to rebellion by her rough manner. At dinner one night, Calamity, looking out of the window, sees a ragged boy feeding Tommy grass. Just then the gardener enters and knocks the boy down and beats Tommy. Calamity immediately rushes out and discharges the man on the spot. To reward the boy, she makes him Tommy’s valet. The boy tells her that his mother is the washerwoman on her estate and when Calamity sees the poor woman hard at work her heart is touched and she invites both the woman and boy to dine with her. This aggravates the servants very much. In the meantime, the social secretary arrives and plans a brilliant social campaign for Calamity Anne. She sends out invitations to a banquet. Calamity secures several of the invitations and sends same to her cowboy friends back home. The day of the dinner arrives. Calamity is coached carefully by the social secretary on etiquette, and is forced by her to wear the most modern gowns. The guests arrive. Calamity meets them all heartily in her uncouth, western way. The guests, however, are shocked at the boisterousness and the social secretary prods Calamity at each fresh “break.” Calamity imbibing too much liquid refreshment, becomes so boisterous that the guests are about to leave. At this point, the cowboys, whom Calamity invited, arrive, and cause great consternation. This shock is soon followed by another. Her supposed uncle’s two lawyers arrive and inform her that she is not the rightful heiress, and they bring forth the real heiress to the estates. Calamity, however, whose shows have been tight and whose thirst for society has been quenched, is more than willing to relinquish her claim on the estate in exchange for her old clothes. Calamity, Tommy and the cowboys are last seen walking slowly over the trail toward their dear western home.
