Contemporary Shanghai, summer. Xia Qing, a boy who has been wearing hearing aids due to hearing loss, has a deep love for dancing. He gains so much joy just from copying Martha Graham's hand gestures in a dance magazine. A kid with a precocious nature, he sometimes paints his pinky nail red just for that glimpse of beauty. Yet all these passionate pursuits are misunderstood and questioned by his single, deaf mother. Given the opportunity to audition for his favorite dance company once in a blue moon, he has no choice but to return to his body--He seeks his mother's approval and longs to overcome this obscure self-identity crisis, through the silent language on his fingertips.
