is a 2020 American jukebox musical romantic drama film based on the novel of the same name by Jerry Spinelli that debuted on Disney+. The film explores the tense emotions, non-conformity and self-expression of teenagers in high school, and the exuberance of first love.
After Leo Borlock's father died, he began to wear a porcupine tie in remembrance of him. At a new school, he was beaten up, and his tie was cut. Since then, on each birthday, he has received a new porcupine tie from an unknown person, but he does not wear them in public. In high school, Leo (Graham Verchere) plays trumpet in the marching band and helps his friend Kevin Singh (Karan Brar), a member of the A.V. club, host an interview show. One day, a free-spirited girl, Stargirl Caraway (Grace VanderWaal), arrives and makes an impression on Leo when she sings "Happy Birthday" to him on a ukulele in front of the school. Later, while their losing football team, the Mudfrogs, are playing, Stargirl performs a song, "Be True to Your School", that energizes them, and they almost get their first win. Kevin and Leo invite her onto their show, but she politely declines.
