Little Doris Calhoun, of a wealthy English family, makes a playmate of Pierre, a crippled gypsy boy, and drifts away with him and the gypsy band on their wanderings and is seen no more. In twelve years she becomes a great favorite with the gypsies, who have named her Kilmeny, but rather than be married to a brutal fellow, Barouche, she flees the camp. Kilmeny is found wandering in the woods, by Lord Leigh, and he persuades the rather reluctant Lady Leigh to give the ragged little wild thing shelter in the manor. The child of camps and trails at first finds naive delight in mysteries like electric light switches, bath tubs with fickle showers and rugs upon which she can slide beautifully over the hardwood floors. But long dresses trip her, the butler is a thundercloud, and at night she cannot sleep in the closed-in room unless she pulls her little white bed to the window.
