Doris Mason, a pretty sixteen-year-old girl whose mother is dead, develops into a terrible flirt, although a perfectly harmless and innocent one. She decides she is in love, and her father finding her somewhat difficult to manage, sends for her Aunt Becky. To break her wild nature, the aunt decides Doris must be sent to school. Stuart Howard, a young man, twenty, who lives near the Mason home, is in love with Doris. She has encouraged him since childhood, unwittingly. She cannot resist the temptation of flirting with other young men. Stuart is in a continual state of jealousy and always on the lookout to save her from committing herself too deeply. Even at the boarding-school she strikes up a flirtation with her music master, Signor Cheesi, and elopes with him from the school. She is caught and saved just in time by Stuart. A surprise is sprung at the end when Signor Cheesi's wife appears with her baby. Doris escapes back to college without being found out.
