Zuzia – 12, has been training vaulting for two years and has extraordinary role topping the acrobatic pyramid. She is «flyer» lifted by the stronger and more experienced vaulters-«base». Another intensive season begins. During training sessions it becomes apparent that the girl has lost some of her grace and lightnes. At first the coach blames the «base» but they admit that Zuzia is to big to lift her. It became clear that she is «just growing» and her role is given over to a younger girl.
