Starr es una chica de dieciséis años que vive entre dos mundos: el barrio pobre de gente negra donde nació, y su escuela situada en un elegante barrio residencial blanco. El difícil equilibrio entre ambos se hace añicos cuando ella es testigo de la muerte a tiros de su mejor amigo, Khalil, a manos de un policía. A partir de ese momento, todo lo que Starr diga acerca de la aterradora noche que cambió su vida podrá ser usado de excusa por unos y como arma por otros. Y lo peor de todo es que, tanto los de un lado como los de otro, la tienen en el punto de mira y amenazan con poner en riesgo su vida.

Sixteen-year-old Starr Carter moves between two worlds: the poor neighborhood where she lives and the fancy suburban prep school she attends. The uneasy balance between these worlds is shattered when Starr witnesses the fatal shooting of her childhood best friend Khalil at the hands of a police officer. Khalil was unarmed. Soon afterward, his death is a national headline. Some are calling him a thug, maybe even a drug dealer and a gangbanger. Protesters are taking to the streets in Khalil's name. Some cops and the local drug lord try to intimidate Starr and her family. What everyone wants to know is: what really went down that night? And the only person alive who can answer that is Starr. But what Starr does—or does not—say could upend her community. It could also endanger her life.
