After the tragic death of star volleyball player Caroline "Line" Found, a team of dispirited high school girls must band together under the guidance of their tough-love coach in hopes of winning the state championship.

Everyone knows that growing up is hard, and life is no easier for high school junior Nadine (Hailee Steinfeld), who is already at peak awkwardness when her all-star older brother Darian (Blake Jenner) starts dating her best friend Krista (Haley Lu Richardson). All at once, Nadine feels more alone than ever, until the unexpected friendship of a thoughtful boy (Hayden Szeto) gives her a glimmer of hope that things just might not be so terrible after all.
