当代，上海，夏日。因听障而从小携带助听器的中学生男孩夏青热衷舞蹈，会跟着舞蹈杂志里玛莎·格兰姆的相片而手舞足蹈。早熟的他也像所有爱美的孩子一样，会用红水笔给自己的指甲盖上色。然而，这些热忱却颇为自己单亲的聋人母亲所不解和质疑。

Contemporary Shanghai, summer. Xia Qing, a boy who has been wearing Cochlear Implants due to hearing impairment, 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.
