After a family move, Bilal and his sister Ayesha attend a new school where they find out that they may be the only Muslim students there. Bilal sees his sister bullied on their first day, so he worries about being teased himself, thinking it might be best if his classmates didn't know that he is Muslim. Maybe if he tells kids his name is Bill, rather than Bilal, then they will leave him alone. But when Bilal's teacher Mr. Ali, who is also Muslim, sees how Bilal is struggling. He gives Bilal a book about the first person to give the call to prayer during the time of the Prophet Muhammad. That person was another Bilal: Bilal Ibn Rabah. What Bilal learns from the book forms the compelling story of a young boy grappling with his identity.
