Meet Camilla, a teenager like many others and like many others somehow special. She lives in a quiet city in Northern Italy, she's a good student, she has a conflicting relationship with her sister Francesca and a dream that her mother doesn't understand, an Eastern woman, pragmatic and hard working, unlike her father, who's more "maternal". Camilla wants to be a ballet dancer and an upcoming audition to be accepted in a prestigious academy is a great opportunity. Meet Sara, another aspiring ballet dancer, who disrupts Camilla's life, like an unrelenting summer wind. Sara is one year older, she's charismatic and sexy; her father is wealthy and her mother is never there. Provoking affectionate moments, defining decisions, twists and turns will shift their relationship in an unexpected direction, changing Camilla's life forever.
