Omar and friends have been saving their pocket money for centuries so they can have the ultimate Nerf Blaster battle. But when Omar discovers that his mosque is in trouble, they decide to donate their pennies. When that turns out not to be enough, they decide to raise money by doing chores, selling home-baked cookies and holding a talent show.
Everything goes perfectly, until the money suddenly disappears mysteriously. Can they find out who stole the money before the mosque has to close? And what is Omar's sister Maryam hiding in her room?
