Subaru and her twin brother Kazuma dream of becoming ballet dancers, but their father discourages their passion. After Kazuma's death from a hereditary illness, dancing becomes Subaru's only happiness, and she yearns to lose herself in dance. Her life takes a dramatic turn when she runs into cabaret owner Isuzu, who recognizes Subaru's talent and trains her in her nightspot. However, to become a professional ballerina, Subaru has to overcome harsher challenges than merely satisfy the cabaret drunkards. Spurred on by her rivalling dance companions, Subaru enters an international dance competition to vie for recognition and a scholarship to any top ballet company in the world. Subaru and her companions soon discover that there are more to compete than the championship, and tests of friendship, betrayal and self-worth come one after another. Gradually the youngsters learn about themselves as dancers, as persons and as friends.
