In New York, businessman Billingsley goes to see Dr. Brewster, the head of the Palmer Medical Foundation, to ask for psychiatric help for his ward, heiress Jane Palmer. The businessman is upset as Jane has managed to squander her entire inheritance, yet refuses to accept its consequences. Billingsley is sent to handsome young psychiatrist Dr. Enright, who states that he can easily cure the young lady of her spendthrift ways. Soon after, while Enright watches, Jane attempts to purchase some expensive jewelry, only to be told that her line of credit has been revoked. When Jane's chauffeur, Milton, quits outside the jewelry store, she has a series of automobile accidents while attempting to drive herself home. Enright comes to her aid, then offers himself as Milton's replacement. Jane returns home to discover that a police auction of her belongings is being planned. Refusing to accept the reality of her poor financial state, Jane agrees to hire Enright, but after all of her possessions have been sold, Enright admits his true profession and mission, and tells her that she must return to her childhood home in Arizona to face the long-repressed fears that have caused her condition. While Jane and Enright travel cross-country, her grandmother, Cactus Kate Palmer, receives a telegram telling of Jane's imminent arrival. Although Stanley Gardner, Jane's old boyfriend, believes that the young heiress is returning home to rekindle their relationship, Kate immediately surmises that Jane is in need of money, but refuses to give her a dime. Enright tells Kate of Jane's psychological problems, but the old woman simply dismisses them as an inherited family trait. Jane, in turn, tells Kate that she is trying to help Enright overcome his own bitterness toward women. Without money from her grandmother, Jane decides to mine for gold in her grandfather's deserted mine. Stanley then arrives and attempts to serenade Jane, who fails to recognize him at first. That night, Jane's romantic attentions are directed at Enright, who kisses her in the moonlight, but comes to his senses just as Stanley returns. After Jane confesses her attraction to Enright, Stanley challenges the "tenderfoot" to a duel, but is shocked to discover that the psychiatrist is an expert marksman. The next morning, Jane tells Kate that she is giving up on Enright and gold mining, but the old woman convinces her to give each a second chance. Digging exactly where her grandmother tells her, Jane strikes gold just before Enright is about to leave. Afraid that he will leave her forever, Jane tells Enright that she is having spells and strange dreams, but he recognize her ruse, and knows that Kate "salted" Jane's gold mine. Enright stays on, however, and news of Jane's gold strike soon fills the newspapers and causes a gold rush. In order to ripen Enright's jealousy, Jane tells the psychiatrist of her plans to marry Stanley. The plan fails when Enright attempts to sneak away on the night of Jane and Stanley's wedding. Enright is stopped by a shotgun-toting Kate, but is then saved when Kate mistakenly assumes that a government agent who wants to buy the "Lost Hope" mine for its silver reserve has come to arrest her for "salting" it with gold. Learning of Enright's departure, Jane leaves Stanley at the altar and goes after the psychiatrist. Back in New York, the staff of the Palmer Foundation becomes concerned with the listless behavior of Enright, but they soon realize its cause when Jane arrives with Billingsley. Jane then corners Enright in his laboratory and informs him that they are in love and meant to be together. Despite his years of medical study, the overwhelmed psychiatrist can do nothing but scream and accept his fate.
