Capernaum (or Chaos) tells the story about Zain (Zain al-Rafeea), who is a Lebanese child who sued his parents for "crime" in giving him life. As Zain grows from streetwise, brave child, to a hardened 12 year-old "adult", he flees his neglectful parents. He survives by his own means on the streets. Rahil is an Ethiopian migrant worker who gives him shelter and food while Zain cares for her son Yonas. Later, Zain is jailed for violent crimes and eventually seeks justice at a courtroom.
