When 11-year-old Kimberly Chang and her mother emigrate from Hong Kong to Brooklyn squalor, she quickly begins a secret double life: exceptional schoolgirl during the day, Chinatown sweatshop worker in the evenings. Disguising the more difficult truths of her life, like her secret love for a factory boy who shares none of her talent or ambition, Kimberly learns to constantly translate not just her language but herself back and forth between the worlds she straddles.
