Summary
A cameraman travels to countries where he finds refugees and listen to their stories, which is mainly about how was their life at their country and how they are dealing with the language barrier after moving to a safer country.
The meaning of the title
I think the title tell us that no where can be more home than the place were grown up and lived with our family, but by learning the language of a country and becoming able to communicate can make a country like your home.
Message
Language is tool that connect us with everyone in this world. It is a wonderful way of education for those who are trying to continue their life in a new place by working and studying hard. Language is a motivation for them.
Problem and solution
As the people interviewed said, their birth circumstances will always govern their lives. There are many countries that don't accept many of those people's passport and nationality, so they don't have much choice where to emigrate. More developed countries should accept more of those people having difficulties in their home country. They will do no harm. They are just looking for a better and safe place to live with their family.
