Teenage Joon is a Korean immigrant living in the Bronx of the 1980s. Her parents have crumbled under the weight of her father's infidelity; he has left the family, and mental illness has rendered her mother nearly catatonic. So Joon, at the age of thirteen, decides she would be better off on her own, a choice that commences a harrowing and often tragic journey that exposes the painful difficulties of a life lived on the margins. Joon's adolescent years take her from a homeless shelter to an escort club, through struggles with addiction, to jobs selling newspapers and cosmetics, committing petty crimes, and finally toward something resembling hope.
