Alice Roland, a poor girl, is snubbed by her companions at high school, and her only admirer is a crippled youth, Roy Gordon. While touched to the quick by the coolness of her associates, her social aspirations are not destroyed, and, reading a romance concerning "Castles in Spain," she conceives the idea of creating some similar situation for her own delectation, and lets her friends share the secret. Her castle in England is shown in a series of "dissolves" as Alice tells the story of her new wealth. The scheme works, and she attends a fashionable lawn party in a borrowed gown. But suspicions are aroused, her plan is discovered, and the girls call upon her mother. Of course, the poor woman knows nothing of Alice's "castle" in the air, tells the truth, and over-ambitious Alice is again ostracized. Shortly after this, poor Roy, who has been wrought up over her story of fictitious wealth, receives a letter from an attorney telling him that he is the sole beneficiary to a $50,000 estate. He goes abroad to visit a German specialist to be cured, if possible, of his physical inferiority. Two years pass, and Alice, through natural aptitude, has been able to support her mother in comfort. One day she is surprised to receive a letter from Roy, stating that although the surgeon had failed him, he is coming back to ask of her an all-important question. The old love flames in her breast, her heart is moved with pity, and she accepts him. Then he straightens up. His lameness has been really cured, and the ambitious girl comes into her own, so her castle in Spain becomes indeed reality.
