A streetwise 12-year-old Lebanese boy, Zain, runs away from home after a fallout with his poor negligent parents. He attempts to survive in the cruel streets of Beirut along with Ethiopian migrant worker Rahil, who provides him with shelter and food, and Zain takes care of her baby son in return. Zain later gets jailed for committing a violent crime, and finally seeks justice in a courtroom as he sues his parents in protest of the life they have given him.

Prisons and detention centers are actively present in the film. When the film introduces the abusive parents of Zain, it shows that they smuggle tramadol into prison by soaking clothes in it and letting them dry. Also, during the first scenes, Zain is seen coming out of detention in what is actually the rough Roumieh Prison. In addition to the authenticity of the prison, the inmates in the film were real and little intervention was made by the production team to alter the decor of the prison cells.
