Promise of Pisa (2019)

Smart second generation Amsterdam Moroccan Samir 'Sam' Zafar adores big brother Mohammed 'Mo', who makes him promise to become the family's first graduate, being gifted enough to enter a famous music school as trumpeter. Sam spares no effort after me gets arrested and jailed for drug robbery, and even makes posh, rich autochthonous friends: shy IJsbrand Versluys and his sister Iris, who becomes his lover. Sam never learned to musical notation and is ready to throw everything away when Mo gets convicted to a long jail term after betrayal by his accomplice, and seems to have lost all interest in Sam and his career, but the tide turns.
