It’s Not a Gun chronicles the triumphs and travails of al-Kamandjâti (the violinist), a summer music school in Ramallah for Palestinian children. Soaring spirits prevail through the film’s plentiful music, while the school’s founder, violinist Ramzi Aburedwan, and his multi-national cohorts face daily problems ranging from obstruction at checkpoints to efforts by vigilante religious extremists to shut them down.
