Gaza. Synonymous to so many with conflict, destruction and despair but to Mohammed Assaf, and his sister Nour, Gaza is their home and their playground. It's where they, along with their best friends Ahmad and Omar, play music and football and dare to dream big. Their band might play on secondhand, beaten-up instruments, but their ambitions are sky-high.

For Mohammed and Nour, nothing less than playing the world-famous Cairo Opera Hall will do. It might take them a lifetime to get there but, as Mohammed will find out, some dreams are worth living for.
