Armed with a rifle, two Morrocan boys set out to look after their family's herd of goats. In the echoes of the desert, they decide to test the rifle but the bullet goes farther than they thought it would. In an instant, the lives of four separate groups of strangers on three different continents collide. Caught up in the rising tide of an accident that escalates beyond anyone's control are a vacationing American couple, a rebellious deaf Japanese teenager and her father, and a Mexican nanny who, without permission, takes two American children across the border. None of these strangers will ever meet; in spite of the sudden, unlikely connection between them, they will all remain isolated due to their own inability to communicate meaningfully with anyone around them.
