Avi and Hamudi are two boys who live in Jerusalem's Old City -- Avi in the Jewish Quarter and Hamudi in the Muslim Quarter. To each boy, the other's neighborhood is an alien land. And although neither boy knows it, both are caring for the same beautiful white stray cat. One day the boys follow the cat as she travels the winding streets and crosses the boundaries between the city's quarters. And on this journey something wonderful happens, as unexpected as a snowfall in Jerusalem.
