The life of seventeen-year-old Xuan is anything but ordinary: She lives and works with her mother and sister in a recycling center surrounded by things others have thrown away. One day, at the suggestion of a boy she likes, she tries to escape into the life of a normal teenage girl.

At 20, Ling balances boxing and helping with her mother's lunchbox business, all while her family quietly unravels. Her parents fake harmony, but when her father brings home a new "girlfriend," the illusion is shattered. Refusing to look away, Ling endures the blows - bloodied and tear-streaked. In facing reality head-on, she discovers a deeper truth: only with honesty in her heart do her punches carry real weight.
