The author travels to different parts of the world that include Belfast, Cyprus, U.S.-Mexico border, Palestine and even Montreal in Canada. His quest is to understand the rationale for building these walls. From the many conversations with these refugees, he discovers their plight of being stuck in camps near the walls with continued efforts to cross over or around the barricade to get on the other side for a better life.
No matter where the wall is erected, it is not a solution. Instead it generates hate, fear, feelings of separation and division. As a result it becomes more of a problem that is fortified in grief and loss of dignity for the refugees. As Di Cintio takes the reader into these areas it becomes evident that the author portrays a hopeless situation with no solution.
