A small doll is living in a doll house in the attic and dreams of becoming a ballet dancer. The viewer not only watches the movie but also virtually interacts with the doll in the course of the story by handing her a white “Feather”, the symbol of courage and encouragement. When the doll feels discouraged or encounters difficulties in the story, a soft and airy “Feather” appears in front of the viewer. Each time the viewer hands the “Feather” to the doll, she grows up a little and takes a step closer to making her dream come true.
