One of the directors, Anne-Sophie Gousset, was inspired by her own childhood memories when writing the screenplay for this tender and almost poetic short film, which shows the close relationship between two sisters as time passes and they grow up. Whether in a stroller, a cart behind a bicycle or on a skateboard or sled, the older sister takes the younger one, who is deprived of the use of her legs, into a joyful whirlwind. Although one of them can neither walk nor run, the fluidity of the animation highlights the incessant movement that unites the two girls – thus the spiral on a snail’s shell becomes the contour of a hill, then a mountain and, lastly, a bicycle wheel. Their shared joy is also accentuated by the jazz-inspired music and the restrained colouring. This uses the texture of oil pastel, in an otherwise stylised graphic universe, which retains the look of the first pencil sketches. With great finesse, the directing duo thus tells the story of a situation of disability experienced by two little girls who have grown up feeling complicity and solidarity.
