Katherine Bradley, known as "Kit," is an orphan and heiress. At an early age she is placed in a fashionable and select seminary for young women. Kit, by means of her fascinating daring, her unlimited cash, and her lovable personality, enlists the cooperation of all the girls in any affair which she undertakes. She so impresses the principal of the school with her open-heartedness that she is given permission to drive her car from four to five o'clock each day. The story opens on the day of the annual play given by the young women of Miss Smythe's Select Seminary. The question passes from mouth to mouth, "Where's Kit Bradley? She's our leading man." A search is instituted which results in finding a note in Kit's room saying that she has taken her car out for a drive. The principal is horrified that her charge should be out without a chaperon, and determines that such an action shall not be repeated. In the meantime, Kit, speeding along the country roads far from home, has an accident. A tire is blown. Kit is perplexed. Then a handsome young man comes along and offers assistance. She accepts it, and promises to meet him on the next afternoon. This arrangement is not carried out quite as Kit planned. Arriving at school very late in the evening, she finds it necessary to enter through an open window. Quickly slipping into a kimono to cover her street clothes and getting into bed. Kit faces an indignant principal who enters her room, with a story of a nerve-wracking toothache which keeps her awake. The next afternoon when Kit would take her usual spin, Miss Smythe reminds her that she must take a chaperon. Kit takes her, but makes the ride so hazardous that the chaperon, when told that the car is not the kind that can go slowly, is glad to be left by the wayside, while Kit takes a spin and returns for her. Kit keeps her tryst. Among the trees she and Cameron enjoy a picnic luncheon, but while this meal is in progress a passing tramp sees Kit's classy new roadster, likes it, and takes it. Cameron takes her in his car and on the wayside they pick up the outraged chaperon, who believes not a word of the little story and hurries the culprit to Kit's guardian. To save herself, Kit announces that she is engaged to the artist, and this is confirmed by Cameron. Brought before the guardian, he recognizes in Cameron an old-time friend, gives his consent, and after reciting a passage from the will of Kit's father that her fiancé must not see her for six months after the engagement, disappears in time for Kit and Cameron to become really and truly engaged. The idea of not seeing her newly found fiancée for six months, is not to Kit's liking, besides, she is just a bit jealous, for he is an artist. So Kit persuades her guardian to take her to a performance of Elsie Janis in "The Fair Co-Ed." From the production she obtains an inspiration that determines her future course of action. Kit changes clothes with a servant and enters Cameron's studio as a slavey. Toddling back and forth in the performance of her menial duties of serving and dusting, she keeps an eye on Cameron and notes those who are constantly coming and going. They are stylish; they are beautiful; they are cultured. Then, too, there is in the studio a fascinating blonde model. Kit must change her tactics and be some or all of these things. She will be beautiful. For surely he, with his artistic temperament and taste, will most appreciate that quality. She, too, will be a model. As Carlotta, the Queen of Italian beauties, she agrees to pose for Cameron. And then, just for the sheer joy of it, and because in Miles Smythe's select school she had learned the art as "leading man," Kit arrayed herself in all the paraphernalia of an up-to-the-minute "chap." She visits the studio and by flashing unlimited coin and even boasting about the large sums she has "on" her. Kit proceeds to win the affections of the beautiful blonde who has been flirting with Cameron. Cameron has seen through the little disguises all the while, but now that he is confronted by a "man," he feels licensed to treat him as a man. He smokes a vicious cigar, blows smoke in Kit's face, and presses her to drink with him. This is too much; she will reveal her identity at once, will or no will. "Guardy," passing Cameron's studio, recognizes Kit's car standing outside, and without ceremony enters and stands behind the young couple as Kit commences to reveal to Cameron her real identity. He sees the lay of the land and makes to them an unexpected and startling disclosure. There probably never was such a wedding. What an assembling of rarely beautiful girls and brave courtly men; a canopy of unflecked blue mountains standing black against the sky and extending off into misty nothingness and great stretches of green and flowers. Kitty was at last married to Cameron.
