Ambrosia is a sweet little girl, of tender heart and of loving disposition, who lives near to nature in fancy and ideals. Her mother dies, and she is sent to an aunt in the city, whom Ambrosia calls "Aunt Grouchy," to be reared as her own child. The aunt is of dignified and austere disposition, far different from Ambrosia's dead mother, and the atmosphere is a decided change from the freedom of country life and the tenderness of mother love. Ambrosia makes friends with the boy next door, and these two greatly enjoy their romps and play together. Ambrosia's cousin is in love with a poor young man, and her mother objects to his attentions desiring for her daughter an advantageous marriage, regardless of the girl's wishes or thoughts of love. "Aunt Grouchy" is a disciple of Hindu mystics, and consults the "Swami," seeking his aid. The "Swami" practices hypnotism upon the daughter of "Aunt Grouchy," influences her to send a note breaking off the affair with the young man, and finally kidnaps the girl and holds her for ransom. Ambrosia and the boy next door discover where the girl is held a prisoner, and inform the police. While the den of the kidnappers is being raided, the "Swami" is at "Aunt Grouchy's" in the act of collecting the ransom money, under guise of a tribute to the Buddhist's god, but when the Secret Service men arrive and arrest him, his true character is exposed. The raid is accomplished at a critical moment, the girl is saved from harm, and when "Aunt Grouchy's" eyes are opened she realizes her past shortcomings. Conquering her proud disposition, she gives her sanction to her daughter's marriage to the poor young man and Ambrosia lives happily ever after.
